Defi nition of congruent segments STUDY TIP When writing a proof, organize your reasoning by copying or drawing a diagram for the situation described. With very few exceptions, only teaching jobs require such skills as ability to prove geometric theorems. Given: TP B: Prove that when a transversal cuts two paralle l lines, alternate interior and exterior angles are congruent. In the above diagram, the angles of the same color are equal to each other. \(\overline{AB}\) is the tangent passing through the point P. The tangent makes \(\angle \alpha\) with the chord PQ. Theorems include: vertical angles are congruent; when a transversal crosses parallel lines, alternate interior angles are congruent and corresponding angles are congruent; points on a perpendicular bisector of a line segment are exactly those equidistant from the segment's endpoints. 7.
