The triangle ABC has sides of the following lengths: AB = 24, BC = 7, and AC = 25.
Let M be the midpoint of AB. What is the length of CM?	Pick
A) 1	B) root139	C) 12	D) root193	E) 16
Since 242 + 72 = 252, triangle ABC is a right triangle. Thus, MBC is also a right   triangle and CM2 = BM2 + BC2 = 122 + 72 = 193.   correct answer root193
