**Why trapezoid is not a parallelogram?**

In general they are **not**, but they can be. Both are quadrilaterals. A **trapezoid** has one pair of parallel sides, whereas a **parallelogram** has two pairs of parallel sides. It is possible that this pair is also parallel, in which case the shape is also a **parallelogram**.

Furthermore, is a parallelogram always a trapezoid?

It depends. A **Parallelogram** is a quadrilateral with two ses of parallel sides. If you use definition A then **parallelograms** and **trapezoids** are mutually exclusive, that is it is impossible to be both. So under definition A, a **parallelogram** is never a **trapezoid**.

Likewise, why is a parallelogram not the same type of quadrilateral as a trapezoid? **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**. Some rectangles may be squares, but **not** all rectangles have four congruent sides.

Correspondingly, is it possible to draw a quadrilateral that is not a parallelogram and not a trapezoid?

Yes. However be aware that there are two competing definitions of a **trapezoid**. Def #1: A **Trapezoid** is a **quadrilateral** with exactly one set of parallel sides. So you could either **draw a quadrilateral** with **no** parallel sides or a **quadrilateral** with two sets of parallel sides (this would **make** it a **parallelogram**).

Why are trapezoids and kites not parallelograms?

**Trapezoids**. Definition: A **trapezoid** is a quadrilateral with exactly one pair of parallel sides. If we forget to prove that one pair of opposite sides is **not** parallel, we do **not** eliminate the possibility that the quadrilateral is a **parallelogram**.

###
Is a rhombus a trapezoid yes or no?

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

###
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**.

###
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**.

###
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 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**.

###
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**.

###
Does a rhombus have 4 right angles?

A square **has** two pairs of parallel sides, four **right angles**, and all four sides are equal. It is also a rectangle and a parallelogram. A **rhombus** is defined as a parallelogram with four equal sides. No, because a **rhombus does** not **have** to **have 4 right angles**.

###
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.

###
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** — it is a quadrilateral with two pairs of parallel faces. But it is also a **rectangle** — it is a quadrilateral with four right angles.

###
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**.

###
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.

###
What are the types of quadrilateral?

**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.

###
Is a kite 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.
