Question

In this triangle, D is the midpoint of AB and E is the midpoint of BCIf AC = 36 what is the length of DE?

Answer 1

A. 18

Explanation:

Recall: the Mid-segment Theorem states that the length of the mid-segment theorem of a triangle is half the length of its third side.

DE = ½(AC) (Triangle Mid-segment Theorem)

AC = 36 (given)

Plug in the value

DE = ½(36)

DE = 18
