LO 5 C 4 5 C ------- 10 A B 3 A B 3 Your friend gives you the right triangle above and to the left and says, "Bisecting an angle is really easy. Take triangle ABC. If I wanted to bisect CAB, all I need to do is find the midpoint of BC. The ray that goes from A through the midpoint of BC will cut CAB in half, because it cuts the side BC in half." Your friend then sketches the triangle above and to the right.
