**Trapezoid-** a quadrilateral in which one pair of opposite
sides are parallel. DC is parallel to AB.

The two sides of the trapezoid that are parallel are called
**bases.** The two sides that are not parallel are called**
legs**.

** Isosceles Trapezoid-** a trapezoid in which the
two legs are congruent. Each pair of

* The height of a trapezoid is a perpendicular line segment that joins the two bases.

To find the **area of a trapezoid**, we must add the lengths
of the two bases together, multiply the sum by the height, and
then multipy that product by 1/2. Therefore, Area = 1/2 * height
* (base1 + base 2 ).

*Problems: Area of a Trapezoid*

1) The height of a trapezoid is 6cm, the bases are 10 cm and 24 cm, find the area.

2) The area of a trapezoid is 226 sq. m., the bases are 4 m and 20 m, find the height.

3) In an isosceles trapezoid, the legs are 6 cm, the bases are 10 cm and 36 cm, find the height.
