acute angle
an angle that measures less than 90 degrees
An acute angle is an angle that measures less than 90 degrees but greater than 0 degrees. It is called ‘acute’ because it is sharp and pointed, like an acute angle in geometry.
In geometry, angles are measured in degrees. An angle with a measure of 90 degrees is called a right angle. Therefore, any angle that measures less than 90 degrees is an acute angle.
Examples of acute angles include the angles formed by the hands of a clock at any time earlier than 3 o’clock, the angles formed by the slanted roof of a house, or the angles formed by two intersecting lines where the opening between them is less than 90 degrees.
The opposite of an acute angle is an obtuse angle, which measures greater than 90 degrees but less than 180 degrees.
