Vertical Angles
Two lines intersect to create two pairs of vertical angles. One pair consists of angles A and B while the second pair consists of angles C and D.
Vertical angles share a common vertex
while bounded by the same pair of lines but reside opposite to each
other. Such angles are congruent, and conseqently, have equal
measurements. As visible from figure above, ∠A =∠B and
∠C =∠D.
