How to find interior angle of regular polygon

Here we will learn about interior angles in polygons including how to calculate the sum of interior angles for a polygon, single interior angles and use this knowledge to solve problems. Interior angles are the angles inside a shape. They are the angles within a polygon made by two sides:, how to find interior angle of regular polygon. The number of triangles a polygon can be split into is always 2 less than the number of sides.

A polygon close polygon A polygon is a 2-dimensional closed shape with straight sides, eg triangle, hexagon, etc. Polygons can be regular or irregular. If the angles are all equal and all the sides are equal length it is a regular polygon. All the interior angles in a regular polygon are equal. The formula for calculating the size of an interior angle is:. Calculate the size of the interior angle of a regular hexagon close hexagon A polygon with six sides. If the side of a polygon is extended, the angle formed outside the polygon is the exterior angle.

How to find interior angle of regular polygon

A polygon is a two-dimensional geometric figure that has a finite number of sides. The sides of a polygon are made of straight line segments connected to each other end to end. They can have any number of sides. Regular polygons have sides and angles of the same length. Many of the polygons like triangles, squares, and rectangles are used extensively for various purposes. To find the measure of one interior angle , we divide the result by n. For example, let's consider a 3-sided regular polygon, that is, an equilateral triangle. We use the formula, and substitute n with 3. Now, if we divide it by n, that is, 3, we get 60, which is the measure of an interior angle of a triangle. Note: The particular formula is true for only regular polygons, that is, where all the angles are the same, and does NOT cover other cases.
