Area of a Trapezoid  Lesson 113
Today we talked about the area of a trapezoid. To find this, we started with a trapezoid (the red one), made a copy of it (the yellow one), and rotated it 180 degrees:
Next, we translated it up to form a parallelogram (the combination of both trapezoids). Using the parallelogram area formula, we were able to find a formula for the area of the trapezoid:
We then defined a median of a trapezoid and learned about two of its properties:
