Question 1193202: EF
is the median of trapezoid ABCD in the figure below. Use the following theorems to answer the questions.
If three (or more) parallel lines intercept congruent line segments on one transversal, then they intercept congruent line segments on any transversal.
The line segment that joins the midpoints of two sides of a triangle is parallel to the third side and has a length equal to one-half the length of the third side.
Suppose that AB = 11.4 and DC = 17.2.
Find MF.
Find EM.
Find EF.
Find
1/2(AB + DC).

Answer by greenestamps(13195) (Show Source): You can put this solution on YOUR website!

EF=(AB+CD)/2

AB and CD are given; do the calculation.

The other questions can't be answered because point M is not defined.

I would appreciate it if you stop responding if you're not going to help but merely just leave rude comments.

What is rude here is your posting a problem without enough information....

And if you are too lazy to find EF by adding AB and CD and dividing by 2, then I'm not going to help you.
