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 · What are Interior Angles. 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.
What Are Alternate Interior Angles in Geometry? In geometry, to define alternate interior angles we need to check the following listed characteristics: The alternate interior angles are equal in measure. They lie on the alternate sides of the transversal. They lie in between the interior of the two lines.
Learn about Alternate Interior Angles: When two lines are crossed by another line (called the Transversal), Alternate Interior Angles are a pair of angles on the inner side of each of those two lines but on opposite sides of the transversal.
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)

Learn that Alternate Interior angles are angle pairs located on the inner sides of two parallel or non-parallel lines intersected by a transversal. Note that these angles are positioned on opposite sides of the transversal.
