Internal and external angles. In geometry, an angle of a polygon is formed by two adjacent sides. For a simple polygon (non-self-intersecting), regardless of whether it is convex or non-convex, this angle is called an internal angle (or interior angle) if a point within the angle is in the interior of the polygon.
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 angles that lie inside a polygon formed by the sides are called interior angles. The following image shows interior angles of a triangle and a pentagon. Note that the number of interior angles in a polygon is always equal to the number of sides. Interior angles examples: Interior Angles of a Triangle. A triangle has three interior angles.
6 Φεβ 2023 · Consecutive interior angles are pairs of angles on one side of a line—called a “transversal”—that crosses two other lines. The Consecutive Interior Angle Theorem states that when the two lines crossed by the transversal are parallel, the consecutive interior angles add up to 180°.
An Interior Angle is an angle inside a shape: Another example: Triangles. The Interior Angles of a Triangle add up to 180°

Interior Angle. 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".
