An Interior Angle is an angle inside a shape: Another example: The Interior Angles of a Triangle add up to 180°.

Here we will learn about angles in polygons including how to calculate angles in polygons using a variety of methods and an overview of interior and exterior angles

The exterior angle of a polygon is formed by any side of the polygon and the extension of its adjacent side. Exterior angles and interior angles are supplementary and form a linear pair.

Activity: How do you find angles in a polygon? Complete this interactive activity to better understand how to calculate angles in a polygon. Then put your knowledge to the test.

So, our new formula for finding the measure of an angle in a regular polygon is consistent with the rules for angles of triangles that we have known from past lessons.

The following diagrams give the formulas for the sum of the interior angles of a polygon and the sum of exterior angles of a polygon. Scroll down the page if you need more examples and …

An angle of a polygon is the measure of the angle formed by two sides of the polygon at a vertex. Angles of polygons are an important concept in geometry, as they help us understand the …

We know that a polygon is a two-dimensional multi-sided figure made up of straight-line segments. The sum of angles of a polygon is the total measure of all interior angles of a polygon.

Before they begin, explain to the pupils the concept of ‘total interior angle’ for a shape. (The total you get when you add the interior angles from each corner). Refresh prior learning that the …

First, let's recall what an exterior angle in a polygon is. An exterior angle is an angle located between an original side and the extension of an original side - a side that extends outside the …
