Name Per Date Ch3 Review Use the figure for Exercises 1–10, suppose a || b and c || d. 1. 1 and 5 are what kind of angles? 2. 9 and 8 are what kind of angles? 3. Which angle could you show is congruent to 11 to prove a || b? 4. If m6 = 50, then find m11. Justify. 5. If m2 = 70, then find m6. Justify 6. If m1 = 130, then find m5. Justify Find the values of the variables. 7. 10. If a||b and b Draw a diagram. 8. ^c and c 9. ^ d, and d || a, then what is the relationship of lines b and d? Determine whether the following pairs of lines are parallel, perpendicular, or neither. 1 11. y = 2x + 1 12. y = x + 4 13. y = 4x + 1 3 2x + y = 7 3x + y = 2 4x + y = 3 14. What is the equation of the line parallel to y = x 1 that contains the point (1, 2)? Graph it. 15. What is the equation of the line perpendicular to y = 1 x + 1 that contains the point (2, 1)? 2 16. Line AB contains points (2, 1) and (1, 8). What is the equation of the line parallel to line AB that contains point (0, 2)? Constructions- Practice! Know how to construct with compass and straight edge: - a congruent segment - a congruent angle. - a angle bisector. - a parallel line. - a perpendicular bisector and perpendicular line that goes through a given point. Definitions: 1) What are Skew Lines? 2) What are Parallel Lines? 3) What are Perpendicular Lines?
