acute angle
An angle less than 90 degrees
An acute angle is an angle that measures between 0 and 90 degrees. It is smaller than a right angle (which measures exactly 90 degrees) and greater than a reflex angle (which measures more than 180 degrees).
If two lines intersect, the angle formed between those lines with a measure between 0 and 90 degrees is called an acute angle. For example, in a right triangle, the angles opposite the legs are acute angles, while the angle opposite the hypotenuse is a right angle.
It is worth noting that the term acute has roots in the Latin word acutus, which means sharp or pointed. This can be a helpful way to remember the meaning of an acute angle, as it has a pointy, narrow appearance. The symbol used to represent an acute angle is a small circle with a diagonal line, with the vertex of the angle located at the center of the circle.
