## What is a trapezoid?

A Trapezoid is a quadrilateral with only one pair of parallel sides

## Try moving side a and side c

Which 2 sides (a,b,c,d) were parallel?

## What is the median of a trapezoid?

A line segment located half-way between the two bases.

## Median of a Trapezoid

## Examine line segments f, g, i, & j

## Now, examine line segments k, h, & l

How would you describe the relationship between the length of the bases (k & h) to the length of the median (l)?

What would be the correct formula for finding the median (l) with bases k & h?
