Interior Angles of Polygons. An Interior Angle is an angle inside a shape: Another example: Triangles. The Interior Angles of a Triangle add up to 180°. Let's try a triangle: 90° + 60° + 30° = 180°. It works for this triangle. Now tilt a line by 10°: 80° + 70° + 30° = 180°. It still works! One angle went up by 10°, and the other went down by 10°.

Here you will learn about interior angles of a polygon, including how to calculate the sum of interior angles for a polygon, single interior angles, and how to use this knowledge to solve problems. Students will first learn about interior angles of a polygon as part of geometry in high school.
Angles in polygons relate to the interior and exterior angles of regular and irregular polygons. Interior angles are the angles within a polygon made by two sides. We can calculate the sum of the interior angles of a polygon by subtracting 2 from the number of sides and then multiplying by 180º .
PROBLEMS INVOLVING INTERIOR ANGLES OF A POLYGON. Find the value of x in the following problems, give brief reasons for your answers. Problem 1 : Solution : Number of sides of the polygon given above = 5. Sum of interior angles of given polygon = (n - 2)180°. = (5 - 2)180°. = (3)180°. = 540°.
Topic Specification. Interior and Exterior Angles Revision. The interior angles of a shape are the angles inside the shape. The exterior angles are the angles formed between a side-length and an extension. Rule: Interior and exterior angles add up to 180\degree.
