Geometry with Measure Name: __________________ Date: _________ Pd:_____ Chapter 3 Mid-Chapter Review For Exercises 1–5, suppose a || b and c || d. (1pt each) 1. If m6 = 50, then find m11. 2. If m2 = 70, then find m6. 3. If m1 = 130, then find m5. 4. If m7 = 110, then find m10. 5. If m4 = 45, then find m12. 6.) Name the exterior angle and its corresponding remoter interior angles. (3pts) Solve for each marked angle: (1pt each angle) 7.) 8.) m3 m1 m5 9. The angle measures of ∆ABC are represented by x + 8, x – 3, and x – 38, what is the measure of each angle? Show work. (6pts) m4 Open Response: (8pts) A right triangle has acute angle measures in the ratio 2:3. A. Draw a figure representing this triangles and label the angles. B. Write and solve an equation to solve for the measures of the angles. C. Find the measure of each angle. D. What must be true of the two acute angles of every right triangle? Use the figure for Exercises 1–10. For Exercises 1–3, suppose a || b and c || d. 1. 2 and 10 are what kind of angles? 2. 3 and what angle are alternate interior angles? 3. 9 and 8 are what kind of angles? 4. Which angle could you show is congruent to 11 to prove a || b? 5. What relationship between 6 and 11 shows c || d? Find the values of the variables. 11. 12. 13. 14.
