Midsegment of a Trapezoid
Below is trapezoid ABCD. Answer the following questions.
1. How can you verify that segment EF is the midsegment of trapezoid ABCD?
2. Calculate the following: (AB + DC)/2. Is this measure equal to any other lengths in the diagram? Make a conjecture about the midsegment of a trapezoid. Then check the “Show relationship” box to check your answer.
Adjust the trapezoid by dragging its points. Does this relationship still hold?
