Question

If FE is a midsegment of ABCD, find DF.
A. 2
B. 3
C. 5
D. 6

Answer 1

C

Explanation:

Remark

A midsegment is 1/2 the size of the side that it is parallel to.

Equation

6x - 6 = 2*(x + 3) Remove the brackets

6x - 6 = 2x + 6 Subtract 2x from both sides

6x - 2x - 6 = 6 Combine

4x - 6 = 6 Add 6 to both sides

4x = 6 + 6 Combine

4x = 12 Divide by 4

x = 12 / 4

x = 3

==================

Find DF

But that's not the answer.

DF = x + 2

DF = 3 + 2

DF = 5
