A flat surface named with a capital cursive letter or by three letters. __________6. A portion of a line with one endpoint that extends in one direction. __________7. Drawn arrowheads on both ends and named by two letters or lowercase cursive letters. For questions 8 ­10, use the figure. 8. What is another name for line l? __________ 9. Name three points on Plane P. ___________ 10. Name the intersection of planes P and B. ________ 1 Determine what each notation represents: 1. AB 2. AB 3. AB 4. AB 5. Given that BD bisects <ABC, solve for x. Then find m<ABC. A D (4x+6)o B 38o C 6. Name an angle supplementary to <SBA D M U S B A 2 3 15 4 5 Distance and Midpoint Review Given points A(‐5, 4) and B(1, ‐3), find the following: 1. The midpoint of AB 2. The length of AB 3. If B is the midpoint of AC, find the coordinates of the missing endpoint C. 6 Given points C(‐1,5) and D(2, ‐1), find the following: 4. Find the midpoint of CD. 5. Find the length of CD 6. If D is the midpoint of CE, find the coordinates of the missing endpoint E. 7 1.5 – Describe Angle Pair Relationships Complementary Angles – the sum of 2 angles equals 90o. Ex: Supplementary Angles – the sum of 2 angles equals 180o. Ex: 8 Adjacent Angles – 2 angles that share a common vertex and side. Ex: B 9 A linear pair is 2 adjacent angles whose noncommon sides are opposite rays. Ex: Vertical Angles – are 2 angles whose sides form 2 pairs of opposite rays. Ex: 10 Page 19 11
