Applet informally illustrates to the student that the sum of the measures of the interior angles of any quadrilateral is 360 degrees, and that the sum of the measures of the exterior angles of any quadrilateral is 360 degrees. This applet is a revision of the one found at http://tube.geogebra.org/m/1878165. It was revised in order to help students develop the formula for the sum of the measures of the interior angles of any n-gon = 180(n - 2).
Two pages of introduction to polygon vocabulary, interior angle sum, exterior angles, naming, and parts of the polygon. Twelve practice problems involve solving from variables, determining the number of sides of a polygon, and finding interior and exterior angles. Answer key included. The one-page reference sheet is a great way for SPED and ESL/ESOL students to have a quick way to access the information they need for polynomials. Happy Solving! from the miss jude math! shop
