Right angle: If the measure of the angle between two rays is exactly equal to 90 degrees or π/2, then the angle is called a right angle. Acute angles: An angle which is measuring less than 90 degrees is called an acute angle.There are special words, and I'll talk about more types of angles in the next video. But if an angle is less than 90 degrees, so, for example, both of these angles that we started our discussion with are less than 90 degrees, we call them "acute angles." So this is acute. So that is an acute angle, and that is an acute angle right over here.Angles and Triangles Unit 7th Grade CCSS. $ 9.50.
