Theorem 6-13 Triangle Angle Bisector Theorem An angle bisector of a triangle divides the opposite side into two segments whose lengths are proportional to the lengths of the other two sides. Theorem 6-14 Proportional Perimeters and Areas Theorem If the similarity ratio of two similar figures is a b, then the ratio of their perimeters is , and the If two points are equidistant from the endpoints of a segment, then they determine the perpendicular bisector. Carefully detail the proof of the Basic Theorem on Perpendiculars. Theorem 8.3 - Through a given point of a given line there passes a plane perpendicular to the given line.

Triangle similarity is another relation two triangles may have. You already learned about congruence, where all sizes must be equal. Proof #1 of Theorem (after B&B) Let the angle bisector of BAC intersect segment BC at point D. Since ray AD is the angle bisector, angle BAD = angle CAD. The segment AD = AD = itself. Also, AB = AC since the triangle is isosceles. Thus, triangle BAD is congruent to CAD by SAS (side-angle-side).
