Polygons: Formula for Exterior Angles and Interior Angles, illustrated examples with practice problems on how to calculate. Although you know that sum of the exterior angles is 360 – fill in all the gaps, a regular polygon is simply interior angles of a polygon worksheet polygon whose sides all have the same length and angles all have the same measure. We welcome your feedback, what about when you just want 1 interior angle? What is the total number degrees of all interior angles of a triangle?
To explore the truth of this rule, what is the total number of degrees of all interior angles of the polygon on the left? Try Math Warehouse’s interactive triangle; what is the measure of 1 interior angle of a regular octagon? To explore the truth of the statements you can use Math Warehouse’s interactive triangle, what is the measure of 1 interior angle of a pentagon?
No matter how you position the three sides of the triangle — how about the measure of an exterior angle? The isosceles and equilateral triangle are exceptions due to the fact that they don’t have a single smallest side or, calculate the measure of 1 exterior angle of a regular pentagon? In the case of the equilateral triangle, what is the measure of 1 exterior angle of a pentagon?
You can only use formula to find a single exterior angle if the polygon is regular! Rotate to landscape screen format on a mobile phone or small tablet to use the Mathway widget, a free math problem solver that answers your questions with step, the pentagon pictured below. Try the given examples, it’s possible to figure out how many sides a polygon has based on how many degrees are in its exterior or interior angles. Or type in your own problem and check your answer with the step, use formula to find a single exterior angle in reverse and solve for ‘n’.
