Defined, the triangle proportionality theorem states that if you draw a line parallel to one of the sides of a triangle that also crosses the other two sides, then that line will divide the two sides in a proportional way.
Isosceles Triangle Theorem. If two sides of a triangle are congruent, then the angles opposite those sides are congruent. Converse also true: If two angles of a triangle are congruent, then the sides opposite those angles are congruent. We will practice using these theorems to help us solve the following exercises.
