Web3; 5; 10; Example 3: Find the measure of each exterior angle of a regular polygon of 20 sides. Solution: The polygon has 20 sides. So, n = 20. Sum of the exterior angles of polygons = 360° So, each exterior angle = 360°n = 360°20 = 18° Example 4: The sum of the interior angles of a polygon is 1620°. How many sides does it have? Solution: WebClassifying Polygons . A polygon is any closed planar figure that is made entirely of line segments that intersect at their endpoints. Polygons can have any number of sides and angles, but the sides can never be curved.The segments are called the sides of the polygons, and the points where the segments intersect are called vertices.The easiest …

WebJan 31, 2024 · Using the Diagonal Formula. 1. Define the formula. The formula to find the number of diagonals of a polygon is n (n-3)/2 where “n” equals the number of sides of the polygon. Using the distributive property this can be rewritten as (n 2 - 3n)/2. You may see it either way, both equations are identical. WebFind the length (in centimeters) of the side labeled x. Two similar four-sided polygons are shown side by side. The left sides are vertical, the top and bottom sides are horizontal, and the right sides travel down and to the right from the top sides. The polygon on the left has the following labeled sides. The left and top sides are labeled 2 cm. WebJun 3, 2024 · 1) no of triangles with only one side common with polygon, if we take any one side of a n-sided polygon and join its vertices to the remaining vertices, except the vertices adjacent to vertices of the line taken above, we get triangles with only one side as common i.e. for 1 side we get (n-4) triangles $\implies$ n(n-4) triangles for n sides ... chipping norton probus club
