If an angle is acute, how can we know if it is an interior angle or an exterior angle?


An interior angle is an area between the rays that make up an angle and extending away from the vertex to infinity.

Any angle that is on the inside of shape is called an interior angle. Any angle that is on the outside of shape is called an exterior angle. An exterior angle is made by extending one of the lines of the shape beyond the intersection point.

If given angle is acute, it can be considered an interior angle if it is inside a shape and an exterior angle if outside the shape.
