Two right angles; A supplementary angle can be made up of two right angles. Distributivity of Multiplication over Addition. A linear pair is pair of two adjacent angles, whose outer arms fall in the same line. Find their measures. Supplementary. Two angles are said to be supplementary angles if they add up to 180 degrees. Two angles /_A are vertical (formed by two intersecting lines) and acute (smaller than 90^o). When two adjacent angles form a straight line, they are supplementary. A right angle is an angle which is exactly 90 degrees. 130. Prev Adjacent, Vertical, Supplementary, and Complementary Angles. And I noted here that these do not have to be adjacent. bhoirramakant bhoirramakant 28.09.2020 Math Secondary School Q6. (iv) Can two adjacent angles be supplementary?
