Question 1 of 10 multiple choice: select the best answer and click "submit." which of the following is not true about the median of a trapezoid? a. the median connects the midpoints of the legs of a trapezoid. b. the length of the median is half the sum of the lengths of the bases. c. the median is parallel to the bases of a trapezoid. d. the median connects the midpoints of the bases of a trapezoid.

A is true as it is pretty much the definition of a median.
B is true and can be demonstrated with a trapezoid's area.
If you were to draw a median (see definition above) on a trapezoid, cut the pieces in half, and then match up one of the sides, you would get a parallelogram!

C is true. You can prove it in a similar fashion to the midline theorem.
D is not true, of course, because it directly contradicts A.
