Measuring Exterior Angles Geogebra 2) click on the point tool (2nd square) and choose "point on object." click anywhere outside the triangle on the ray you just created. 3) find the measure of the exterior angle formed by clicking on the angle tool (8th square) and choosing "angle"; then click c, b, and your new point (in that order). 4) drag any point and make observations. The exterior angles of a triangle, quadrilateral, and pentagon are shown, respectively, in the applets below. you can control the size of a colored exterior angle by using the slider with matching color. feel free to move the vertices of these polygons anywhere you'd like. note: for the quadrilateral & pentagon, the last two applets work best.

Topic: angles this worksheet is a demonstration illustrating why the exterior angle of a triangle equals the sum of the two opposite interior angles. click fold to fold the top part of the triangle over, then rearrange to rotate and translate the combined interior angle until it overlaps the exterior angle. This demonstrates that the measure of an exterior angle of a triangle is equal to the sum of the measures of the two remote interior angles.
