## Exterior Angles of a Pentagon – Formula and Examples

The exterior angles of a pentagon are formed when we extend the sides of the pentagon. These angles have a total sum of 360°. Also, the sum of an exterior angle and its corresponding interior angle is equal to 180°. Therefore, we can use these properties to find the...

## Exterior Angles of a Polygon – Formula and Examples

The exterior angles of polygons are formed when we extend the sides of a polygon. The sum total of these angles is always equal to 360°. Therefore, if the polygon is regular, we can divide 360° for the number of sides to find the measure of an exterior angle of the...

## Sum of Interior Angles of a Pentagon

The sum of interior angles of a pentagon is equal to 540°. This is true regardless of whether the pentagon is regular or irregular. In the case of regular pentagons, we can determine the measure of each interior angle by dividing the total sum by 5. However, in the...

## Interior Angles of a Pentagon – Formula and Examples

Pentagons have a sum of interior angles of 540°. Therefore, in the case of regular pentagons, each interior angle measures 108°. Irregular pentagons have angles of different measures, but their sum is always equal to 540°. Here, we will learn more about the interior...

## Intersecting Lines – Properties and Examples

Intersecting lines are formed when two or more lines share one or more points of intersection. For the lines to intersect, they must have different slopes and be non-parallel. When two lines intersect, two pairs of opposite vertical angles are formed. Here, we will...
