# How To Geometry parallel lines proofs worksheet: 9 Strategies That Work

The following proof of Theorem 3-12 relies on the idea that through a point not on a given line you can draw a line parallel to the given line. Proof of Theorem 3-12 Given: #ABC Prove: m&A + m&B + m&3 = 180 Proof: By the Protractor Postulate, you can draw so that m&1 = m&A.Then, &1 and &A are congruent alternate interior angles, so 6 .Geometry Worksheets Listed Alphabetically: Algebraic Representations.

Introduction to proofs: Identifying geometry theorems and postulates ANSWERS C congruent ? Explain using geometry concepts and theorems: 1) Why is the triangle isosceles? PR and PQ are radii of the circle. Therefore, they have the same length. A triangle with 2 sides of the same length is isosceles. 2) Why is an altitude? AB = AB (reflexive ... complementary), then the lines are parallel. 3. If two lines are cut by a transversal so that (alternate interior, alternate exterior, corresponding) angles are congruent, then the lines are parallel. 4.
