Understanding Acute Angles: Definition and Examples

acute angle

An acute angle is an angle that measures less than 90 degrees

An acute angle is an angle that measures less than 90 degrees. In other words, it is an angle that is smaller than a right angle.

To better understand acute angles, let’s consider a few examples.

– A right angle measures exactly 90 degrees, so any angle that measures less than 90 degrees is an acute angle. For instance, an angle measuring 45 degrees is acute because it is smaller than 90 degrees.

– A straight angle measures exactly 180 degrees, so any angle that measures less than 180 degrees but greater than 90 degrees is also an acute angle. For example, an angle measuring 120 degrees is acute because it is smaller than 180 degrees but larger than 90 degrees.

– An obtuse angle, on the other hand, is an angle that measures more than 90 degrees but less than 180 degrees. It cannot be classified as an acute angle because it exceeds the limit of 90 degrees.

In summary, an acute angle is any angle that is smaller than a right angle, measuring less than 90 degrees.
