Name _________________________________ Geometry R HW 1.3 Date: ___________ Period: ______ #1-7: For each of the following, a) write the term which is defined. b) draw a picture. 1. ___________________ the union of two non-collinear rays that share a common endpoint 2. ___________________ a ray which divides an angle into two congruent angles, each half the original angle 3. ___________________ an angle whose measure is less than 90 4. ___________________ an angle whose measure is greater than 90 5. ___________________ an angle whose measure is exactly 90 6. ___________________ the common endpoint of the sides of an angle 7. ___________________ two rays with a common endpoint which form an angle whose measure is 180 8. Using a compass and straightedge, construct an angle on BC congruent to A List the construction steps: B A. C 9. BD bisects ABC. a) If m ABD = (4x + 18) and m ABC = 52 , find the value of x. b) If m ABD = (y2 – y) and m DBC = 72 , find the value of y. c) If m CBD = 30 and m A B D C ABC = (5a + 15) , find the value of a. d) If m ABD = (w2 + 3w) and m of ABC. 10. Using a compass and straightedge, construct the bisector of A DBC = (5w + 8) , find the measure A. List your construction steps.
