These worksheets will teach your students how to correctly calculate exterior angles for different shapes.

How do you determine the measures of each exterior angle of a polygon? Polygons are a form of two-dimensional shape made of regular and straight lines. Some examples include triangles, quadrilaterals, pentagons, and hexagons. All polygons have interior and exterior angles. While we know that the angles, we see in a polygon at every corner is the interior angle, but what is the exterior angle? Exterior angles are those that formed between any side of a shape, and a line extended from the next side so, how do you measure each exterior angle? For regular polygons, all you have to do is, divide 360 by the number of sides or angles that the polygon has. Simple as that!

These worksheets are grounded on all types of different shapes. The goal is to understand the value of angles that are outside of the primary shape that you are given. You will be given triangles to many sided polygons. We even go as far as asking you to contemplate a 30-sided object. The basic fundamental rule you need to grasp is that the sum of the exterior angles is always equivalent to 360 degrees. These worksheets explain how find the measure of exterior angles. Your students will use these sheets to practice calculating the exterior angles of different shapes.
