1 3 2 Triangle Sum Theorem The sum of the angle measures in a triangle equal 180° m<1 + m<2 + m<3 = 180°
exterior angle remote interior angles 2 1 3 4 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 remoteinterior angles m<4 = m<1 + m<2
