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.

An Interior Angle is an angle inside a shape: Another example: Triangles. The Interior Angles of a Triangle add up to 180°
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".
The interior angles of a polygon are those angles at each vertex that are on the inside of the polygon. There is one per vertex. So for a polygon with N sides, there are N vertices and N interior angles. For a regular polygon, by definition, all the interior angles are the same.
Definition. Angles that are inside a shape are referred to as interior angles, and interior angles can also refer to angles that are located in the region enclosed by two parallel lines and a transversal. https://www.storyofmathematics.com/wp-content/uploads/2023/01/m12-interior-angle.mp3.
