WebAn angle which is measuring less than 90 degrees is called an acute angle. This angle is smaller than the right angle (which is equal to 90 degrees). For example, ∠30 o, ∠45 o, ∠60 o, ∠75 o, ∠33 o, ∠55 o, ∠85 o, etc. are all acute angles. Let us see some examples here to understand. Example: See the figure below: WebThe angle bisector in geometry is the ray, line, or segment which divides a given angle into two equal parts. For example, an angle bisector of a 60-degree angle will divide it into two angles of 30 degrees each. In other words, it divides an angle into two smaller congruent angles. Given below is an image of an angle bisector of ∠AOB.
