## How are triangles and trapezoids similar?

A triangle is a two-dimensional shape with three sides and three angles. A trapezoid is a four-sided, two-dimensional shape with two parallel sides. Trapezoids have two bases. Those are the sides that are parallel.

## What fraction of a trapezoid is a triangle?

It takes 3 triangles to cover the red trapezoid, so therefore each triangle is worth 1/3.

## How many triangles can you make if you divide a trapezoid diagonally?

The diagonals of a trapezoid divide the interior region into four nonoverlapping triangles.

## How do you find the missing measurement of a trapezoid?

Since this problem provides the length for both of the bases as well as the total perimeter, the missing sides can be found using the following formula: Perimeter= Base one Base two (leg), where the length of “leg” is one of the two equivalent nonparallel sides.

## How do you solve a trapezoid problem?

Solution to Problem 1:

1. Use the sine definition in a right triangle to find the height h of the trapezoid. sin D = h / CD.
2. Solve the above for h. h = CD sin D = 2 sin 40.
3. Use the formula of the area to obtain the following equation.
4. The above equation has only one unknown: AD.
