If two parallel lines are cut by a transversal, then the two pairs of same-side interior angles are supplementary. ∠2and∠4are same side interior angles. The angle pairs created have cool relationships. Eight angles are formed. The acute angles are all congruent. 8. transversal. AG Line t is a transversal of lines a and b. ∠1, ∠2, ∠7, ∠8 Alternate interior angles are on opposite sides of the transversal and inside the parallel lines. Get creative! If the transversal is not perpendicular to the parallel lines, then four angles are acute and four are obtuse. When the transversal cuts through parallel lines, the alternate exterior angles, alternate interior angles, corresponding angles, and vertical angles are congruent while the same-side exterior and same-side interior angles are supplementary.

LESSON Reteach 3-3 Proving Lines Parallel Converse of the Corresponding Angles Postulate If two coplanar lines are cut by a transversal so that a pair of corresponding angles are congruent, then the two lines are parallel. • A line that intersects two or more other lines is called a transversal. 3.Use the properties of parallel lines to determine congruent angles . The acute angles are all congruent. ��p�� In some cities, where the blocks are rectangles or squares, the streets generally run parallel to each other. A. • Parallel lines are two lines in a plane that never intersect or cross. 1… Given: ∠1 ≅ ∠3 ∠1 ≅ ∠3 ∠1 ≅ ∠3 are corresponding angles. Construct a line and label two points on the line A and B. The obtuse angles are all congruent. Reteach Lines and Angles continued A transversal is a line that intersects two lines in a plane at different points. Give an example of each type of angle pair. ANGLE PAIRS in two lines cut by a transversal. Eight angles are formed. A B 1 2 /1 and /2 form a linear pair and /1 > /2, so a ' b. Perpendicular Transversal Theorem In a plane, if a transversal is perpendicular to one of two parallel lines, then it is perpendicular to the other line.
