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
8th Grade math game for Triangle Sum & Exterior Angles Theorem. Perfect for small groups, independent practice, whole class review, and progress monitoring. This middle school math game covers ALL Common Core math standards related to Triangle Sum Theorem and Exterior Angle Theorem in 8th Grade math.
Interior & Exterior Angles of Polygons Cut, Paste, Solve, Match Puzzle Activity
Students will solve problems involving interior and exterior angles of polygons. They will have to find the sum of the interior angles of a convex polygon, sum of the exterior angles of a convex polygon, each interior angle in a regular polygon and each exterior angle in a regular polygon.
This purchase includes a PowerPoint, video lesson and video notes on the triangle exterior angle theorem. The PowerPoint is designed for whole classroom instruction while the pages may be individually printed as worksheets. Common Core Alignment 8.G.A.5Use informal arguments to establish facts about the angle sum and exterior angle of triangles, about the angles created when parallel lines are cut by a transversal, and the angle-angle criterion for similarity of triangles.
In this activity, students will practice applying the Exterior Angle Theorem as they color to reveal a beautiful, colorful pattern! Students will find measures of indicated angles or variables and then color their answers on the mandala according to the color given.
