Example 1: Exs.
Consider, for instance, the pentagon pictured below. Divide by the number of sides, to figure out the size of each exterior angle in this unit of regular polygons pdf worksheets for 8th grade and high school students. For regular polygons, by definition the angles all have the same measure, so we can divide the angle sum by n the number of angles to find the measure of a specific angle. Students will see that they can use diagonals to divide an n-sided polygon into n-2 triangles and use the triangle sum theorem to justify why the interior angle sum is n-2 They will also make connections to an alternative way to determine the interior … An exterior angle of a polygon is formed by extending only one of its sides. The number of triangles is always two less than the number of sides. Angles A student-based discovery activity that explores the sum of the interior angles of a polygon by deconstructing the polygons into triangles, and then calculating the sum of degrees for every triangle that could be made.
This preview shows page 1 - 2 out of 6 pages. Some of the worksheets for this concept are 6 polygons and angles, Sum of angles in polygons work answer key, Polygons quadrilaterals and special parallelograms, Sum of polygons, Angles in polygon 1, Interior angle 1, Relationship between exterior and remote interior angles, Interior and exterior angles. The sheets can be used for work in class or as a homework. Sum of interior angles worksheet five pack find the sum of the outside angles. Since the interior angles of a regular polygon are all the same size, it follows that the exterior angles are also equal to one another.
