An angle that measures exactly 90 degrees is called a

Explanation:
Different kinds of angles are named by how many degrees they show. An angle that measures exactly 90 degrees is called a right angle. An acute angle is any angle smaller than 90 degrees. An obtuse angle is bigger than 90 degrees but less than 180. A straight angle is exactly 180 degrees and looks like a straight line. So 90 degrees fits the definition of a right angle, which is why this term is used for this angle. For example, the corner of a square forms a right angle.
