Points L, M, and N are collinear. You are given LM = 13 and LN = 20. What is a possible value of MN?

Question

IXL problems for geometry

Answer 1

Note there are two different possibilities...

(a) If L lies between M and N, then MN is 13 + 20 = 33

(b) If L lies on one side of both points M and N, then MN = 20 - 13 = 7
