WebThis activity has students investigate the interior and exterior angles of polygons. Students construct diagonals and triangles to generalize the sum of interior angles. They compress a polygon to investigate the sum of the exterior angles. Students will also develop a formula for determining an individual interior and exterior angle of a regular polygon. WebThe angle next to an interior angle, formed by extending the side of the polygon, is the exterior angle. Hence, we can say, if a polygon is convex, then the sum of the degree …
What are the angles of a 12 sided polygon? - Answers
Web6 Nov 2011 · Then the exterior angle is 180 - x degrees. x = 5* (180-x) = 900 - 5x So 6x = 900 so that x = 150 degrees. So exterior angle = 30 degrees. If the polygon has n sides (and n angles) the sum of its exterior angles is 30*n But the exterior angles of a polygon add to 360 degrees So 30*n = 360 so that n = 12. ANSWER: 12 sides.
