What is an interior angle. The interior angles of a triangle add up to 180. The consecutive interior angles theorem states that if two parallel lines are cut by a transversal then each pair of alternate interior angles is congruent. Interior angle definition an angle formed between parallel lines by a third line that intersects them.

Interior angle the angle inside two adjacent sides of a polygon internal angle angle the space between two lines or planes that intersect. Interior angle an interior angle is an angle inside a shape. An interior angle is an angle inside a shape.

A polygon has exactly one internal angle per vertex. When we add up the interior angle and exterior angle we get a straight line 180. Interior angles are the angles formed within or inside a shape.

A polygon will have the number of interior angles equal to the number of sides it has. If a polygon has 5 sides it will have 5 interior angles. Since triangles have three angles they have three interior angles.

The inclination of one line to another. Angles a b and. The interior of an angle is the area between the two rays that define it shown in yellow above.

In geometry an angle of a polygon is formed by two sides of the polygon that share an endpoint. In contrast an exterior angle is an angle formed by one side of a simple. Interior angle of a polygon is that angle formed at the point of contact of any two adjacent sides of a polygon.
