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.
Not to be confused with Angel. This article is about angles in geometry. For other uses, see Angle (disambiguation). A green angle formed by two red rays on the Cartesian coordinate system. In Euclidean geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. [1]
Interior angles refer to interior angles of a polygon or angles formed by a transversal cutting two parallel lines. Learn the different meanings with examples.
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.
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°.

5 ημέρες πριν · On many occasions a knowledge of exterior angles may throw light on the nature of interior angles and sides. The sum of the measures of the external angles of any polygon is \(360^\circ\). This is true whatever the number of sides of the polygon is.
