Note: my book rethinking proof has a learning activity with a worksheet and associated sketch in relation to the defining of interior angles in terms of the concept of directed angles so as to extend it in a consistent way to the interior angle sum of a crossed quadrilateral, and crossed polygons in general. Sumof interiorangles. the interiorangles of any polygon always add up to a constant value, which depends only on the number of sides. for example the interior angles of a pentagon always add up to 540 no matter if it regular or irregular, convex or concave, or what size and shape it is. the sum of the interior angles of sum of interior angles of a polygon applet a polygon is given. With respect to polygon, we have four important formulas. among them exterior angle of a regular polygon formula is one. the other formulas are interior angle of regular polygon, sum of interior angles, and sum of exterior angles. now we will learn what is an exterior angle? and also the formula for the exterior angle of a regular polygon.
