A polygon is any 2D shape constructed from a finite number of straight lines. For example, a triangle is a three-sided polygon, and a square is a type of four-sided polygon, and so on. All of these polygons have angles both on the inside and the outside, but what do these angles ...
An Interior Angle is an angle inside a shape: Another example: The Interior Angles of a Triangle add up to 180.
The formula used to find the sum of the interior angles of a polygon is: S=(n-2) × 180°. In this case, n = 4. Therefore, thesum of the interior angles of a quadrilateral is (4-2)×180° =360°. How do you find the measure of an interior angle of a regular polygon?
A regular pentagon and an irregular pentagon Interior Angles A polygon could have 3, 4, 5, or more sides. The number of sides a polygon has is equal to the number of vertices and the number of interior angles it has. The interior angles of a polygon are the angles inside the shape. ...
An octagon is an 8-sided figure. To find the area of an octagon, we use the following formula:where 'a' is the length of one side. Interior angles are the angles inside of a polygon. The sum of the interior angles of an octagon is 1,080 degrees, making each of the eight angles ...

The interior angles of a polygon are the angles between two sides, inside the shape. The Sum of the Interior Angles of a Polygon The sum of the interior angles of a polygon is given by the formula:In this formula, n is the number of sides of the polygon. The formula tells you what...
of one interior angle, we would know the measure of all interior angles. The formula for finding the measure of each interior angle is again determined by the number of sides of the polygon… EXAMPLE # 1 : What are the measures of the interior angles of a regular polygon with 5 sides ...
Inside a Regular Pentagon A regular pentagram can be constructed inside a regular pentagon by drawing itsdiagonals. Draw 2 diagonals each from all the 5 vertices of the pentagon. And your pentagram is ready! Now let us see how to construct a pentagram outside a regular pentagon ...
