If they're parallel, then the corresponding angles are equal. I wanted to be an architect once. 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. Behold the awesome power of the two words, \"perpendicular bisector,\" because with only a line segment, HM, and its perpendicular bisector, WA, we can prove this theorem.We are given line segment HM and we have bisected it (divided it exactly in two) by a line WA. CC.9-12.G.CO.12 That line bisected HM at 90° because it is a given.
