m < 1 = 42....vertical angles are equivalent m < 2 = 180 - (62 + 42) = 180 - 104 = 76.....because < 1 + < 2 + 62 make a straight line which equals 180 m < 3 = 62....vertical angles are congruent m < 4 = 76....because < 4 and < 2 are vertical angles m < 5 = 118....because < 5 and < 1 + < 2 are corresponding angles m < 6 = 180- 118 = 62.....because < 6 and < 5 make a straight line m < 7 = 62...vertical angles (< 6and < 7) m < 8 = 118....because < 8 ad < 5 are vertical m < 9 = 180 - (62 + 42) = 180 - 104 = 76....angles of triangle equals 180 m < 10 = 180 - 76 = 104....straight line equals 180 m < 11 = 104....vertical angles (< 10 and < 11) m <12 = 76...vertical angles (< 9 and < 12)
