What is the interior angle of a quadrilateral?

Angles in a quadrilateral are the four angles that occur at each vertex within a four-sided shape, these angles are called interior angles of a quadrilateral. The measure of interior angles of a quadrilateral always sums up to 360°.

Let the measure of the fourth interior angle be x.

x + 55° + 117° + 120° = 360°

x + 292° = 360°

x = 68°

Hence, the fourth interior angle will be 68°.
