in this lesson our instructor talks about proving angle relationships. She talks about supplement theorem and supplementary angles. She talks about congruence of angles and five angles theorems. She then talks about using angle theorem in example problems. Four complete4 extra example videos round up this lesson.
Supplement Theorem: If two angles form a linear pair, then they are supplementary angles
Congruence of Angles: Congruence of angles is reflexive, symmetric, and transitive
Angles supplementary to the same angle or to congruent angles are congruent
Angles complementary to the same angle or to congruent angles are congruent
All right angles are congruent
Vertical angles are congruent
Perpendicular lines intersect to form four right angles
