What is the definition of an acute angle?

• Lines that intersect to form right angles.

• An angle that is open more than a right angle but less than a straight angle. This angle measures between 90 and 180 degrees.

• An angle that forms a square corner and has a measure of 90 degrees.

• An angle that is open less than a right angle and has a measure less than 90 degrees.
