Interior angles are those that lie inside a polygon. For example, a triangle has 3 interior angles. The other way to define interior angles is "angles enclosed in the interior region of two parallel lines when intersected by a transversal are known as interior angles".

This set of worksheets concentrates on the interior angles of polygons. Interior angles of a polygon are the angles that are found inside the polygon. By definition all the interior angles of a regular polygon are the same, if it is a uniform shape.
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 Angles. The interior angles of a triangle are the angles inside the triangle. Properties of Interior Angles. The sum of the three interior angles in a triangle is always 180°. Since the interior angles add up to 180°, every angle must be less than 180°. Printable & Online Triangle Worksheets. Find missing angles inside a triangle. Example:
Interior angles are all the angles found inside a shape, in this case a triangle (which means we are working with 3 interior angles). The sum of the interior angles is always 180 degrees.
