Complementary angles must be acute. (v) Pair of vertically opposite angles are always supplementary. (iv) Two angles forming a linear pair are supplementary. 100. Enroll in one of our FREE online STEM summer camps. (d) x = 115° true or false: Q is the vertex of Angles-> SOLUTION: - Find one counterexample to show that each conjecture is false.1. Verticle angles are opposite to each other when two lines cross. Solution: Question 2. (c) right (vii) Adjacent angles have a common vertex, a common ……….. and no common ……… 162 o Obtuse. State whether the following statements are true (T) or false (F): (i) Two obtuse angles can be supplementary. Solution: Question 11. A pair of supplementary angles is (a) 55°, 115° (b) 65°, 125° (b) 47°, 133° (d) 40°, 50° Solution: A pair of supplementary angles is 47°, 133°. true or false 1.vertically opposite angles are always supplementary. (xiv) If two lines are cut by a transversal such that a pair of corresponding angles are not equal, then the lines are not parallel. Using the reflex angle, we can find the measure of the acute angle. Solution: Question 14. Then, ∠A + ∠B = 25° + 63° = 88°. (xii) Corresponding angles are on the ……….. side of the transversal.
