Line segment, A, P, intersects segment, R, I, at point, T, with line segments from, A, to, R, and from, I, to, P. Labels as follows: Side, I, T, 8.5, side, T, R, 8, angle, A, R, T, 53 degrees, angle, I, T, P, 29 degrees, angle I, P, T, 98 degrees. Examine the triangles at right. Are they similar? Are they congruent? Explain how you know. Then write an appropriate similarity or congruence statement.

Hint:

Find the measures of the unknown angles, and the lengths of the unknown sides. Does this help prove the triangles are similar?
