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.

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.
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) ?
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.
There is a range of printable geometry sheets, looking at angles in a variety of forms such as right angles, angles on a straight line and triangles. Using these sheets will help your child to: learn how to find a missing angle; know that angles inside a right angle must add up to 90° know that angles on a straight line must add up to 180°
