1. Trapezoids
Section 5-5

2. Definition
A trapezoid is a quadrilateral with only one set of opposite sides parallel.
The parallel sides are called the bases, the non-parallel sides are the legs

3. Isosceles Trapezoid A trapezoid where the legs are congruent.
Theorem:The base angles of an isosceles trapezoids are congruent.

4. Median of a trapezoid The line connecting the midpoints of the legs.
The median is parallel to the bases.
It is the average of the base lengths.

5. Median of a trapezoid cont.
= 4.4 / 2 = 2.2
