Take a look at one of the complementary-angle theorems and one of the supplementary-angle theorems in action: Before trying to write out a formal, two-column proof, it’s often a good idea to think through a seat-of-the-pants argument about why the prove statement has to be true. Theorem 4: Verticals angles are congruent If 2 angles are vertical, then they are congruent. Rating. They can be at any orientation on the plane. ∠1 ∠ 1 and ∠2 ∠ 2 are complementary if ∠1 +∠2 = 90∘ ∠ 1 + ∠ 2 = 90 ∘ Equidistant theorem(cannot use name for shortcut) If two points are equidistant to the endpoints of the segment then the two points form the perpendicular bisector of the segment. Image Transcriptionclose. Game plan: In this proof, for example, you might say to yourself, “Let’s see. Then since they are supplementary, m∠A + m∠B = 180° And since they are congruent, m∠A = m∠B Substituting equals for equals in m∠A + m∠B = 180° m∠B + m∠B = 180° 2m∠B = 180° Divings both sides by 2 m∠B = 90° So ∠B is a right angle And since m∠B = m∠A m∠A = 90° So ∠B is a right angle So it's true that they are both right angles.
