Asked 1/28/2016 11:05:58 AM. 30 and 150 are supplementary angles because 30 + 150 = 180 No, since obtuse angles must be greater than 90 degrees and less than 180 degree, any two obtuse angles would add up to greater than 180 degrees. Can two obtuse angles be supplementary? Solution: Its complementary angle is less than 45°. 2. ∠ PQR is an obtuse angle because its less than 180° and greater than 90°. Every angle has a complement and a supplement. Yes. The straight angle can be formed by adding two right angles. An angle is greater than 45°. Yes ! Relevance. The remaining angle measure of the triangle would have to be negative in that case. (ii) No, because sum of two obtuse angles is more than 180 0. Note: (a) Two acute angles cannot be supplement of each other. Since an obtuse angle angle has degree greater than 90, two obtuse angles produce a sum that is greater than 180 degrees which is impossible. Solution : False If two angles are supplementary angles, then it is not necessary that they are always obtuse angles. (viii) If two lines are cut by a transversal, then each pair of alternate interior angles are equal. Such angles are called a linear pair of angles. True or False? One obtuse angle and one acute angle can make a pair of supplementary angles. Answer Save. sometimes. 4. Is its complementary angle greater than 45° or equal to 45° or less than 45°. 2. Question 8.
