The Interior Angles of a Pentagon add up to 540°The General RuleEach time we add a side (triangle to quadrilateral, quadrilateral to pentagon, etc), we add another 180° to the total:If it is a Regular Polygon (all sides are equal, all angles are equal) ShapeSidesSum of Interior ...
This page includes a lesson covering 'the interior angles of a polygon' as well as a 15-question worksheet, which is printable, editable and sendable. The interior angles of a polygon are the angles between two sides of a polygon. The sum of the interio

1.Any of the four angles formed inside two straight lines when these lines are intersected by a third straight line. 2.An angle formed by two adjacent sides of a polygon and included within the polygon. Compareexterior angle. The American Heritage® Student Science Dictionary, Second Edition...
What is the sum of the measures of the interior angles of a pentagon? In other words, how many degrees are there in a pentagon? There is a formula to find the number of degrees in the interior angles of any polygon. Remember that the three interior angles of a triangle have a sum of...
To extend that further, if the polygon has x sides, the sum, S, of the degree measures of these x interior sides is given by the formulaS = (x - 2)(180). For example, a triangle has 3 angles whichadd up to 180 degrees. A square has 4 angles which add up to 360 degrees. For...
