## What shapes have at least 1 pair of perpendicular sides?

Shape with at least one pair of perpendicular sides is a “right angled triangle”.

**What figures have perpendicular sides?**

Some shapes which have perpendicular lines are:

- Square.
- Right-angled triangle.
- Rectangle.

### What are perpendicular side pairs?

In a square or other rectangle, all pairs of adjacent sides are perpendicular. A right trapezoid is a trapezoid that has two pairs of adjacent sides that are perpendicular. Each of the four maltitudes of a quadrilateral is a perpendicular to a side through the midpoint of the opposite side.

**Which shape has at least one pair?**

A trapezoid has at least one pair of parallel sides. It may have two! You can easily find other definitions for a trapezoid which indicate it only has ONE pair of parallel sides.

#### What is a quadrilateral that has at least one pair of perpendicular sides and at least one pair of parallel sides?

How many pairs of perpendicular sides would you say a rectangle has? PARCC defines a trapezoid as a quadrilateral with at least one pair of parallel sides.

**What shape has 4 pairs of perpendicular sides?**

Like a square, a rectangle has lines that are perpendicular to two other lines. This means it also has four right angles.

## What shape has 3 pairs of perpendicular lines?

I am a 3 sided shape. I have 3 equal sides. All my angles are equal. I have 0 parallel and 0 perpendicular sides. | equilateral triangle. |

I am a quadrilateral (4 sides). All my sides are equal. I have 4 right angles. I have 2 pairs of parallel sides. I have 4 perpendicular lines. | Square |

**Which figure has only one pair of parallel sides and two pairs of perpendicular sides?**

trapezoid

A trapezoid is only required to have two parallel sides. However, a trapezoid could have one of the sides connecting the two parallel sides perpendicular to the parallel sides which would yield two right angles.

### What shapes have at least one vertex?

A cone is a solid three-dimensional figure with a circular base and one vertex.

**What has at least one pair of parallel sides?**

#### Which quadrilateral has only one pair?

A trapezoid is a quadrilateral with exactly one pair of parallel sides.

**What shape has 4 pairs of parallel sides?**

A regular octagon is a shape that has 4 pairs of parallel sides. Each side is parallel to the side that is opposite to it.
