Triangle Sum Theorem & Exterior Angle Theorem

Triangle Sum Theorem The sum of the angle measures in a triangle equal 180° 3 2 1 m<1 + m<2 + m<3 = 180°

Exterior Angle Theorem (your new best friend) The measure of an exterior angle in a triangle is the sum of the measures of the 2 remote interior angles exterior angle remote interior angles 3 2 1 4 m<4 = m<1 + m<2
