Two angles are complementary if the sum of their measures is Two angels are supplementary if the sum of their measures is degrees. 180' 90' These two angles are complementary 55' + 35' = 55' degrees 35' These two angles are supplementary 40' 40' + 140' = 140' degrees Remember that a straight angle is equal to 180' write your answer here Find the value of "X" 50' x= X degees 30' + X = 90' Find the value of "X" A C hint 30' X X= B degrees D hint: remember vertical angles Find the measure of each numbered angle 2 60' 1 m m 1 = 2= degrees degrees 120' Find the missing measure ' ' 10' ' Find the missing measure 50' ' 50' ' 11' Find the missing measures Hint----Remember vertical angles are congruent (equal) 55' ' ' ' Identify as complementary or supplementary 1 2 42' 38' |
