2. Definition of Complementary Angles: If m∠1 + m∠2 = 90°, then
3. Definition of Supplementary Angles: If ∠P and ∠Q are supplementary angles, then
4. Definition of a Right Angle: If m∠ JKL = 90°, then
5. Vertical Angles Theorem: If ∠3 and ∠4 are vertical angles, then
6. Complement Theorem: If ∠S and ∠T form a right angle, then
7. Supplement Theorem: If ∠X and ∠Y form a linear pair, then
8. Congruent Complements Theorem: If ∠1 is complementary to ∠2 and ∠2 is complementary to ∠4, then
9. Congruent Complements Theorem: If ∠J is supplementary to ∠K and ∠J is supplementary to ∠L, then
