Notes 6 1 Angles Of Polygons Youtube In this geometry video, we will discuss polygonscheck out emberlearninglabs for more information. Find the sum of the measure of interior and exterior angles of a polygon.
6 1 Angles Of Polygons Youtube We discuss the sum of the interior and exterior angles of polygons. we also discuss regular vs irregular and convex vs. concave polygons. Each linear pair adds to 180º for a total of n • 180º or 180 n degrees around the polygon. 4. we have already shown that the formula for the sum of the interior angles of a polygon with n sides is 180 (n 2). 5. from the sum of all linear pairs (180 n), subtract the sum of the interior angles (the formula). Scroll down the page for more examples and solutions on the interior angles of a polygon. example: find the sum of the interior angles of a heptagon (7 sided) solution: step 1: write down the formula (n 2) × 180°. step 2: plug in the values to get (7 2) × 180° = 5 × 180° = 900°. answer: the sum of the interior angles of a heptagon (7. 6.1 angles of. that connects outside of the polygon. polygon is when there is a diagonal. concave. connect inside the polygon. polygon is when all of the diagonals. convex. polygon names. sides congruent and all angles congruent.

The polygon can be broken up into three triangles. multiply the number of triangles by 180o to get the sum of the interior angles. show step. 180∘ ×3 = 540∘ 180 ∘ × 3 = 540 ∘. state your findings e.g. sides, regular irregular, the sum of interior angles. show step. The measure of an interior angle of a regular polygon is 150 degrees. how many sides must this polygon have? 24. if one exterior angle of a regular polygon measures 72°, what is the measure of one interior angle? 25. a portion of a regular polygon is shown above.
