Another way to do it is to know that all the exterior angles of any polygon have to add up to. Caddell Prep offers online test prepweb-based math assignmentsand in-person tutoring and test prep. A quadrilateral has 4 sides. Challenge Problem What is the measure of 1 exterior angle of a pentagon? You should notice that every time we add a side, the sum of the angles go up by. Since there are already line segments that connect point A to points B and Dwe only need to draw a line to point C. Let's pick point A to draw lines from. So, each interior angle is. So, if you want to know the sum of the interior angles of a certain polygon, just make a quick chart starting with a triangle at and keep on adding as you increase the sides. Examples of Regular Polygons Regular Hexagon.

## Interior Angles of Polygons

Interior Angles of Polygons. An Interior Angle is an angle inside a shape. interior exterior angles. Another example: interior exterior angles. Polygons - A list of multi-sided figures, their names and regular anges.

A regular polygon is one that has equal sides and equal interior angles.

### Polygons Wyzant Resources

The sum of the measures of the angles of a convex polygon with n sides is (n - 2) A regular polygon is simply a polygon whose sides all have the same length and angles all have the same measure. You have probably heard of the equilateral.

Exterior angles always add up to.

Problem 2 What is the total number of degrees of all interior angles of the polygon? Exercise 2 Find the value of z in the figure below. What this means is just that the polygon cannot have angles that point in. Triangleswhich we have already learned about, are one type of polygon. So, the only type of triangle we could be talking about is an equilateral one like the one pictured below.

## Regular Polygon Angle Calculator

If we have a regular pentagon, which is a five-sided polygon, we know what the sum of the interior angles going to be.

### Interior and Exterior Angles of a Polygon dummies

On the other hand, the sum of interior angles will be different depending on how many sides there are. Notice that we have created two triangles. When you use formula to find a single exterior angle to solve for the number of sidesyou get a decimal 4. You may be asking yourself why the Polygon Interior Angle Sum Theorem works, or if we can use it with any n -gon. There are many more polygons than just triangles and quadrilaterals, however.
