The General Rule. Each time we add a side (triangle to quadrilateral, quadrilateral to pentagon, etc), we add another 180° to the total: So the general rule is: Sum of Interior Angles = (n −2) × 180 °. Each Angle (of a Regular Polygon) = (n −2) × 180 ° / n. Perhaps an example will help: Example: What about a Regular Decagon (10 sides) ?

Interior angles are those that lie inside a polygon. For example, a triangle has 3 interior angles. The other way to define interior angles is "angles enclosed in the interior region of two parallel lines when intersected by a transversal are known as interior angles". How to Find the Sum of Interior Angles?
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.
Interior angles of a polygon. Interior angles are the angles within a polygon made by two adjacent sides. You can calculate the sum of the interior angles of a polygon by subtracting 22 from the number of sides and then multiplying by 180 ∘.180∘.
An Interior Angle is an angle inside a shape. Another example: When we add up the Interior Angle and Exterior Angle we get a Straight Angle (180°), so they are "Supplementary Angles".
14 cze 2023 · Angles that are found inside or within any geometric shape are called interior angles. They are also sometimes called internal angles. A triangle has three interior angles. Similarly a quadrilateral such as a square, rectangle, parallelogram, kite, or a trapezoid has four interior angles.
