1 Answer. **Yes**, a **rhombus** is a special type of **trapezoid**.

Then, Are rectangles trapezoids?

NO. A **trapezoid** is defined (in North America) to be a quadrilateral that has exactly one pair of parallel sides. A quadrilateral with two pairs of parallel sides is called a parallelogram; a parallelogram with right angles is a **rectangle**.

Considering this, What shape is a trapezoid? A **trapezoid** is a 4-sided flat **shape** with straight sides that has a pair of opposite sides parallel (marked with arrows below): **Trapezoid**.

**What is a 4 sided shape called?**

A quadrilateral is **a four**–**sided polygon** with four angles. There are many kinds of quadrilaterals. The five most common types are the parallelogram, the rectangle, the square, the trapezoid, and the rhombus. Move your mouse cursor over the figures at the right to learn more.

**Is a square a trapezoid yes or no?**

**No**. In order for a quadrilateral to be a **trapezoid**, it must have exactly one pair of parallel sides. A right **trapezoid**, therefore, has exactly one pair of right angles. However a **square** would be a right parallelogram (which is the current definition of a rectangle).

**Is an isosceles triangle a quadrilateral?**

This is either a parallelogram (specifically, having congruent diagonals, a rectangle) or an **isosceles** trapezoid. Thus, if the four non-overlapping **triangles** created by the diagonals of a **quadrilateral** are all **isosceles**, the **quadrilateral** must be either a rectangle or an **isosceles** trapezoid.

**Is an equilateral triangle A quadrilateral?**

All regular polygons and isotoxal polygons are **equilateral**. An **equilateral triangle** is a regular **triangle** with 60Β° internal angles. An **equilateral quadrilateral** is called a rhombus, an isotoxal polygon described by an angle Ξ±. It includes the square as a special case.

**Is a trapezoid A quadrilateral?**

**Trapezoids** have only one pair of parallel sides; parallelograms have two pairs of parallel sides. A **trapezoid** can never be a parallelogram. The correct answer is that all **trapezoids** are **quadrilaterals**. **Trapezoids** are four-sided polygons, so they are all **quadrilaterals**.

**What shape is a trapezoid?**

A **trapezoid** is a four-sided **shape** with at least one set of parallel sides. It can have two and be a parallelogram. But, if two sides aren’t parallel, then it’s just the lowly **trapezoid**. So, in a **trapezoid**, the parallel sides are called the bases.

**Is a trapezoid a polygon?**

A **trapezoid** is a four-sided shape with at least one set of parallel sides. The area of a **trapezoid** is the average of the bases times the height. Finally, a **polygon** is a closed, two-dimensional shape with many sides. Everything from a triangle to an octagon to a megagon is a type of **polygon**.

**Is a kite a parallelogram?**

**Yes**. A rectangle is a quadrilateral with 4 right angles. A **parallelogram** is a quadrilateral with 2 pairs of parallel sides. The opposite sides on every **square** are parallel, so every **square** is a **parallelogram**.

**Is rhombus a parallelogram?**

DEFINITION: A **rhombus** is a **parallelogram** with four congruent sides. THEOREM: If a **parallelogram** is a **rhombus**, each diagonal bisects a pair of opposite angles. THEOREM Converse: If a **parallelogram** has diagonals that bisect a pair of opposite angles, it is a **rhombus**.

**What are characteristics of a quadrilateral?**

**Quadrilaterals**. A **Quadrilateral** has four-sides, it is 2-dimensional (a flat shape), closed (the lines join up), and has straight sides.

**Is a rectangle a parallelogram?**

A **rectangle** has two pairs of opposite sides parallel, and four right angles. It is also a **parallelogram**, since it has two pairs of parallel sides.

**How do you know a quadrilateral is not a trapezoid?**

**1 Answer**

- No. A trapezoid is defined as a quadrilateral with two parallel sides. Therefore, the quality of “quadrilateral” is necessary, and this condition is satisfied.
- No. Any other shape can have four sides, but if it does not have (at least) two parallel sides, it cannot be a trapezoid.

**Does a rhombus have 4 right angles?**

**Who invented quadrilateral?**

**Quadrilaterals** were **invented** by the Ancient Greeks. It is said that Pythagoras was the first to draw one. In those days **quadrilaterals** had three sides and their properties were only dimly understood.

**Is a square a rhombus?**

A **rhombus** is a quadrilateral with all sides equal in length. A **square** is a quadrilateral with all sides equal in length and all interior angles right angles. Thus a **rhombus** is not a **square** unless the angles are all right angles. A **square** however is a **rhombus** since all four of its sides are of the same length.

**Is a kite a rhombus?**

In general, any quadrilateral with perpendicular diagonals, one of which is a line of symmetry, **is a kite**. Every **rhombus is a kite**, and any quadrilateral that is both a **kite** and parallelogram is a **rhombus**. A **rhombus** is a tangential quadrilateral. That is, it has an inscribed circle that is tangent to all four sides.

**What is an example of a quadrilateral?**

In geometry, a **quadrilateral** can be defined as a closed, two-dimensional shape which has four straight sides. The polygon has four vertices or corners. We can find the shape of **quadrilaterals** in various things around us, like in a chess board, a deck of cards, a kite, a tub of popcorn, a sign board and in an arrow.

**Is a rectangle always a parallelogram?**

It is true that every **rectangle** is a **parallelogram**, but it is not true that every **parallelogram** is not a **rectangle**. For instance, take a square. It’s a **parallelogram** β it is a quadrilateral with two pairs of parallel faces. But it is also a **rectangle** β it is a quadrilateral with four right angles.

**What makes a quadrilateral special?**

**Special quadrilaterals**: Information sheet

A trapezium is a **quadrilateral** with one pair of sides parallel. A kite is a **quadrilateral** with two pairs of adjacent sides equal. A parallelogram is a **quadrilateral** whose opposite sides are parallel. A rhombus is a **quadrilateral** with all sides equal.

**There are six basic types of quadrilaterals:**

- Rectangle. Opposite sides are parallel and equal.
- Square. Opposite sides are parallel and all sides are equal.
- Parallelogram. Opposite sides are parallel and equal.
- Rhombus. All sides are equal and opposite sides are parallel.
- Trapezium.
- Kite.

**What is not a parallelogram?**

An ordinary quadrilateral with no equal sides is **not a parallelogram**. A kite has no parallel lines at all. A trapezium and and an isosceles trapezium have one pair of opposite sides parallel. A Concave quadrilateral or arrowhead does **not** have parallel sides.

**What is not a parallelogram?**

In Euclidean geometry, a **kite** is a **quadrilateral** whose four sides can be grouped into two pairs of equal-length sides that are adjacent to each other. In contrast, a **parallelogram** also has two pairs of equal-length sides, but they are opposite to each other rather than adjacent.

**Why is a quadrilateral not a parallelogram?**

There are **quadrilaterals** that are **not parallelograms**. is a **quadrilateral** because it has four sides. But it does **not** have two pairs of sides that are parallel, (in fact no two sides are parallel), so this is **not a parallelogram**. A **parallelogram** is a **quadrilateral** with two pairs of parallel sides.

**Is a square a rhombus?**

A **rhombus** is a quadrilateral with all sides equal in length. A **square** is a quadrilateral with all sides equal in length and all interior angles right angles. Thus a **rhombus** is not a **square** unless the angles are all right angles. A **square** however is a **rhombus** since all four of its sides are of the same length.

**Are all parallelograms trapezoids?**

Others define a **trapezoid** as a quadrilateral with at least one pair of parallel sides (the inclusive definition), making the **parallelogram** a special type of **trapezoid**. Under the inclusive definition, **all parallelograms** (including rhombuses, rectangles and squares) are **trapezoids**.

**What kind of shape is a quadrilateral?**

**Quadrilateral**. A **quadrilateral** is a polygon that has exactly four sides. (This also means that a **quadrilateral** has exactly four vertices, and exactly four angles.)

**What are the 7 Quadrilaterals?**

A **rhombus** is a quadrilateral with all sides equal in length. A **square** is a quadrilateral with all sides equal in length and all interior angles right angles. Thus a **rhombus** is not a **square** unless the angles are all right angles. A **square** however is a **rhombus** since all four of its sides are of the same length.

**What does it mean to be congruent?**

**Congruent**. Angles are **congruent** when they are the same size (in degrees or radians). Sides are **congruent** when they are the same length.
