# What is the base of a trapezoid?

## What is the base of a trapezoid?

parallel sides
The parallel sides are called the bases of the trapezoid and the other two sides are called the legs or the lateral sides (if they are not parallel; otherwise there are two pairs of bases).

What are the bases and legs of a trapezoid?

A trapezoid is a quadrilateral with exactly one pair of parallel sides. The parallel sides are called bases, and the other two sides are called legs. Additionally, the midsegment of a trapezoid is the segment joining the midpoints of the legs, and it is always parallel to the bases.

### How do you find the base angles of a trapezoid?

So, if given the measure of one of the upper angles, you know that its base angle is supplementary to it, so subtract its value from 180° to find the measure of the base angle. Then, recall that in an isosceles trapezoid, the base angles are congruent.

What is base one and base two in a trapezoid?

Area formula Recall that the bases are the two parallel sides of the trapezoid. The altitude (or height) of a trapezoid is the perpendicular distance between the two bases.

## What are the two bases of a trapezoid?

Terminology. The two parallel sides of the trapezoid are referred to as the bases of the trapezoid; the other two sides are called the legs.

What is base of triangle?

Answer: The bottom line of a triangle is the base of the triangle, and it can be one of the three sides of the triangle. In a triangle, one side is a base side and the remaining two sides can be the height or the hypotenuse side. Explanation: Let’s draw a diagram of a triangle.

### What are the bases of trapezoid ABCD?

In trapezoid ABCD, BC?? AD. The parallel sides BC and AD are called the bases, and the nonparallel sides AB and CD are legs. Base angles are a pair of angles that share a common base.

What is a leg of trapezoid?

Terminology. The two parallel sides of the trapezoid are referred to as the bases of the trapezoid; the other two sides are called the legs. If the two legs of a trapezoid have equal length, we say it is an isosceles trapezoid.

## What are base angles formed with?

The base angles of an isosceles triangle are the angles formed by the base and one leg of the triangle. The base angles theorem converse states if two angles in a triangle are congruent, then the sides opposite those angles are also congruent.

What is true about the base of a trapezoid?

Because the parallel sides are the only ones that can be bases, even when the trapezoid is drawn with a leg at the bottom and horizontal, it is not a base . It is still a leg. The base is usually the longer parallel side, but if the trapezoid is drawn with the shorter parallel side at the bottom, then it is the base.

### How many bases does a trapezoid have?

A trapezoid has two bases, each of which is one of the parallel sides. The other two sides that aren’t parallel to each other are called the trapezoid’s legs.

Can any side of a trapezoid be called a base?

Recall that a trapezoid is a quadrilateral with exactly one pair of parallel sides. Any side of a rectangle, triangle , or parallelogram can be taken as the base, but only the parallel sides of a trapezoid are called bases.

## What is a trapezoid in real life?

Real-life examples of trapezoids include certain table tops, bridge supports, handbag sides and architectural elements. Since a trapezoid cannot be three-dimensional, many real-life examples of trapezoids are only partly designed with that shape. For example, the surface of a table might be a trapezoid, but its legs and supports are not.
