acute angle
an angle that measures less than 90 degrees – it is less open than a right angle
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, which measures exactly 90 degrees. The word acute comes from a Latin word meaning sharp or pointed, which is fitting because acute angles are sharp and pointed. An example of an acute angle is the angle formed by two lines intersecting at a point, where both lines are slanting upwards and to the right. This angle would measure less than 90 degrees. Acute angles are commonly used in geometry and trigonometry to calculate various properties of shapes and triangles.
