Alternate Exterior Angles - Once two parallel lines are cut by a transversal, who two angles on opposite sides a this transversal and outdoor the paralleling lines (an example below).
An exterior angle of a triangle is equal to the sum of the opposite interior angles. Every triangle has six exterior angles (two at each vertex are equal in measure). The exterior angles, taken one at each vertex, always sum up to 360 ° 360\degree 360°. An exterior angle is supplementary to its adjacent triangle interior angle.The sum of the measures of the angles of a triangle is 180. In the figure at the right, m∠A + m∠B + m∠C = 180.
