Interiorand Exterior Anglesof A Triangleworksheets
Although you know that sum of the exterior angles is 360, you can only use formula to find a single exterior angle if the polygon is regular! consider, for instance, the pentagon pictured below. even though we know that all the exterior angles add up to 360 °, we can see, by just looking, that each $$ \angle a \text{ and } and \angle b $$ are. An exterior angle is when a line is drawn outside of the triangle, extending the angle. the exterior angle is \(\angle {\text{acd\). all the angles inside the triangle are interior angles. a little side note: the exterior angle and the adjacent interior angle (the one connected to it) always add up to 180° because together they form a line.
