10.2 complementary and supplementary angles

Notes Complementary: 2 angles are complementary if they add to 90 degrees. Supplementary: 2 angles are supplementary if the add to 180 degrees.

Supplementary or Complementary? m1 = 34° and m2 = 146° m1 = 23° and m2 = 157° m1 = 45° and m2 = 45°

Find missing angle m1 and m2 are complementary; m1 = 23° m3 and m4 are vertical angles; m3 = 23° m5 and m6 are supplementary; m5 = 23°

Find missing angles m1 and m2 are complementary angles; m1 = 20°. m1 and m2 are vertical angles; m2 = 150°. m3 and m4 are supplementary angles, m3 = 34°. m1 and m2 are complementary angles; m1 = 63°. m1 and m2 are vertical angles; m2 = 15°. m3 and m4 are supplementary angles, m3 = 110°.
