When two lines intersect to make an X, angles on opposite sides of the X are called vertical angles. measure of one vertical angle, an easy starting point is to fill in the measure of the other. B. 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.
