# The Median of a Trapezoid

## Trapezoid

A trapezoid is a 4-sided flat shape with straight sides that has

**a pair of opposite sides parallel**that is also known as**bases.**i.e.**and****The other two sides are known as****legs.**i.e. and The distance (at right angles) from one base to the other is known as the**altitude**or**height.**i.e.*line segment h*## Median

Recall: The median (also called a midline or midsegment) is a line segment half-way between the bases.
i.e.

*line segment m*## Median Length

The median’s length is the average of the two base lengths: .

## Fun Fact:

**You can calculate the area when you know the median, it is just the median times the height:**

## Find the median of this trapezoid.

**Play around with this trapezoid and observe how the area changes.**
