Sum of exterior angles of a regular polygon

Sum of exterior angles: Explore more about sum of exterior angle with solved examples. The number of edges and vertices determines the sum of the corners in a polygon. In a polygon, the two different types of angles are interior angles and exterior angles. In this article, we will cover the sum of exterior angles.

Exterior angles are angles between a polygon and the extended line from the vertex of the polygon. Check out our lessons on interior angles of polygons and sum of the interior angles to find out more. Includes reasoning and applied questions. Exterior angles of a polygon is part of our series of lessons to support revision on angles in polygons. You may find it helpful to start with the main angles in polygons lesson for a summary of what to expect, or use the step by step guides below for further detail on individual topics. Other lessons in this series include:. What is the size of the adjacent exterior angle?

Sum of exterior angles of a regular polygon

The angle between a side of a polygon and an extended adjacent side gives an exterior angle of a polygon. It is an angle formed by a transversal as it cuts one of two lines and is situated on the outside of the line. In this article, we will learn all about the exterior angle of a polygon, Sum of exterior angles, theorems and properties with solved examples. Any closed two dimensional shape with three or more sides is called a polygon. Polygons are named according to the number of sides and the types of angles they have. As the number of sides changes the properties of the polygon change. If the side of a polygon is extended, the angle formed outside the polygon is the exterior angle. The exterior angles of a polygon are the angles present outside of the polygon. They are formed between one of the sides of a polygon and an adjacent side being extended. These exterior angles have their own properties and are used to find out the measure of unknown angles, the number of sides of a polygon etc. That is a common misunderstanding. In all polygons, there are two sets of exterior angles, one that goes around clockwise and the other goes around counterclockwise. Assume that you start your journey from the vertex at angle 1.

In a polygon, there are at least three sides and angles. The internal and exterior angles at each vertex varies for all types of polygons. This means we can divide by 4 to get the solution.

Before going to know the sum of exterior angles formula, first, let us recall what is an exterior angle. An exterior angle of a polygon is the angle between a side and its adjacent extended side. This can be understood clearly by observing the exteriors angles in the below triangle. From the above triangle, the exterior angles Y and R make up a linear pair. Thus, the sum of exterior angles can be obtained from the following formula:.

Thus, the sum of exterior angles can be obtained from the following formula:. Let us check a few solved examples to learn more about the sum of exterior angles formula. Example 1: Find the measure of each exterior angle of a regular hexagon. To find: The measure of each exterior angle of a regular hexagon. Example 2: Use the sum of exterior angles formula to prove that each interior angle and its corresponding exterior angle in any polygon are supplementary.

Sum of exterior angles of a regular polygon

Exterior angles of a polygon are formed when by one of its side and extending the other side. The sum of all the exterior angles in a polygon is equal to degrees. You are already aware of the term polygon. A polygon is a flat figure that is made up of three or more line segments and is enclosed.

Home Maths Exterior Angles of Polygon. Number of sides of the polygon. If the side of a polygon is extended, the angle formed outside the polygon is the exterior angle. You covered the entire polygon perimeter and finished the whole cycle. Download as PDF. The internal and exterior angles at each vertex varies for all types of polygons. A regular polygon has 15 sides. The line segments are called the sides and the point where two sides meet is called the vertex of the polygon. It has to travel along the boundary or the outline of the hexagon to reach again to the starting point. The sum of the interior angles is:.
