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°. Let's try a triangle: 90° + 60° + 30° = 180°. It works for this triangle. Now tilt a line by 10°: 80° + 70° + 30° = 180°. It still works! One angle went up by 10°, and the other went down by 10°. Quadrilaterals (Squares, etc)
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".
8 lip 2021 · Interior angle: An interior angle of a polygon is an angle inside the polygon at one of its vertices. Angle Q is an interior angle of quadrilateral QUAD. Exterior angle: An exterior angle of a polygon is an angle outside the polygon formed by one of its sides and the extension of an adjacent side.
Interior angles are the angles formed inside a polygon, where the sides of the polygon meet. They are an essential concept in understanding the properties of angles, triangles, and the Pythagorean Theorem.
Interior Angle: An interior angle refers to the angle formed within a polygon by two adjacent sides. It is the angle enclosed by any two sides within a closed figure. The sum of interior angles in a polygon depends on the number of sides it possesses.
