The angles that lie inside a shape, generally, a polygon, are said to be interior angles, or the angles that lie in the area enclosed between two parallel lines that are intersected by a transversal are also called interior angles. Learn more about interior angles in this article.

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) ?
Whether you’re a math student or a geometry enthusiast, this article aims to provide you with a comprehensive understanding of interior angles. We will begin by explaining the concept of interior angles in polygons, followed by examples and explanations to enhance your knowledge.
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.
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".
