Points A. B. C are collinear. but they do not necessarily lie on a line in the order named. If AB = 5 and BC = 3. what is the length of AC?a. either 2 or 8 b. either 2 or 4 c. 2 d. 8

Circles H and I have the same radius. JK, a perpendicular bisector to HI, goes through L and is twice the length of HI. If HI acts as a bisector to JK, what type of triangle would HKI be?     A right triangle     B special right triangle     C equilateral triangle     D isosceles triangle

2. Einstein's proof Triangle ABC is a right triangle and CD I AB. Assume CA = a, CB = b, AD=x, DB = y, and AB =c =x+y. Use this diagram to prove the Pythagorean Theorem. C y B D
