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. if <1 and <2 are supplementary and <2 and <3 are supplementary, then <1 is congruent to <3 Congruent Complements Theorem If m<4 + m<5 = 90 and m<5 + m<6 =90, then <4 is congruent to <6 Complementary angles are two angles that add up to 90°, or a right angle; two supplementary angles add up to 180°, or a straight angle. Proposition 1.27 of Euclid's Elements , a theorem of absolute geometry (hence valid in both hyperbolic and Euclidean Geometry ), proves that if the angles of a pair of alternate angles of a transversal are congruent then the two lines are parallel (non-intersecting). Theorem 4: Verticals angles are congruent If 2 angles are vertical, then they are congruent. If two angles are supplementary to two other congruent angles, then they’re congruent. Congruent Complements Theorem. The previous four theorems about complementary and supplementary angles come in pairs: One of the theorems involves three segments or angles, and the other, which is based on the same idea, involves four segments or angles. ∠2 ≅ ∠60° since they are corresponding angles, and m and n are parallel. if two angles are supplementary and congruent then they are right angles Let the first angle be x. If two congruent angles form a linear pair, then the measure of cach angle is See reason 2.). If m ∠1 + m ∠2 = 180 ° and m ∠2 + m ∠3 = 180 °, then, m∠1 ≅ m ∠3 Two angels are congruent if they .....

When working through a game plan, you may find it helpful to make up arbitrary sizes for segments and angles in the proof. Think of this argument as a game plan. Supplementary Angle Theorem (with Illustration) The supplementary angle theorem states that "if two angles are supplementary to the same angle, then they are congruent to each other". Converse of the Alternate Interior Angles Theorem - If two coplanar lines are cut by a transversal so that a pair of alternate interior angles are congruent, then the two lines are parallel. Subtraction Property of Equality: If two quantities are equal, then if the same quantity is subtracted from each of the original quantities, the differences are equal. Kevin walked Three-fourths of a mile in 12 minutes. add to 90. Hence, in this case these two angles are considered congruent.
