What is a vertex? And how does algebra figure into geometry? This program examines all things angular, including acute, right, obtuse, straight, adjacent, complementary, supplementary, and vertical angles. Four theorems are also introduced, along with the reflexive, substitution, and transitive properties. A proof of the congruency of vertical angles is performed as well. (14 minutes)
