4. Classify the triangle by its sides. The lengths of the sides are 9, 9, and 9. A) equilateral B) scalene C) obtuse D) isosceles 7. Line a is parallel to line b and m.(Angle 7 ) = 135 Find m(angle 4) A) 135 B) 145 C) 45 D) 35 8. Find the values of x and y for which the lines are parallel. A) x = 68, y = 72 B) x = 46, y = 72 C) x = 68, y = 74 D) x = 72, y = 68 11.Look at the figure. If Angle 1 Is Congruent To angle 2 , describe the relationship between lines a and b. A) The lines are perpendicular. B) The lines are parallel. C) The lines intersect. D) The lines are transversals. 12. Find the value of x for which the lines are parallel. A) 63 B) 71 C) 64 D) 72
The answer to #4 is A equilateral because all the sides are the same. the sides are equal. # 7 would be c, 45 you have to make sure the sum is 180 #8 is B the same goes for that on fill in x and y. #11 isD And # 12 is c the sum must be 180.
