If two lines are perpendicular, then they meet to form. right angles. Theorem 1.7.1: If two lines meet to form a right angle, then these lines are perpendicular. âif and only ifâ. âiffâ. Theorem 1.7.2: If two angles are complementary to the same angle (or to. congruent angles) then these angles are congruent.
If two angles are complements of the same angle (or of congruent angles), then the two angles are congruent. Congruent Supplements Theorem If two angles are supplements of the same angle (or of congruent angles), then the two angles are congruent. Right Angles Theorem. All right angles are congruent. Same-Side Interior Angles Theorem. If a transversal intersects two parallel lines, then the interior angles on the same side of the transversal are supplementary. Converse also true: If a transversal intersects two lines and the interior angles on the same side of the transversal are supplementary, then the lines are parallel. The sum of the degree measures of the same-side interior angles is 180Â°.
