These angles are congruent. Vertical Angles: Two nonadjacent angles formed by intersecting lines or segments. Also called opposite angles. These angles are congruent. Mar 2311:02 AM Alternate Interior Angles: On alternate sides of the transversal on the inside of the two parallel lines. Two angles are congruent. Complementary Angles: Two angles whose sum is 90 degrees. Alternate Exterior Angles: On alternate sides of the transversal on the outside of the two parallel lines. Two angles are congruent. Supplementary Angles: Two angles whose sum is 180 degrees. Mar 159:32 PM 8 Parallel Lines and Transversals FOLDABLE notes February 24, 2015 A B C 1) What is line A called? 1. Transversal 2) Name a relationship between 5 and 6. 3) Name a pair of Alternate Interior Angles. 2. Linear pair, supplementary angles, adjacent angles 3. 3 and 6, 4 and 5 4) Name a pair of Supplementary Angles. 4. 5 and 6, 3 and 4 5) What do complementary angles add to give you? 5. 90 degrees 6) What do supplementary angles add to give you? 6. 180 degrees Apr 127:50 AM Congruent vs. Similar Congruent: exactly the same size and same shape Similar: same shape but different sizes Mar 227:51 AM 9 Parallel Lines and Transversals FOLDABLE notes February 24, 2015 Mar 229:08 AM 10
