Mathematical types of angles : Each angle has a unique measure and is formed when two rays or lines intersect at a place. Acute, obtuse, right, reflex, and straight angles can all be used to describe these angles of various measurements. Angle pairs come in a variety of shapes and sizes. Let's take a closer look at the various points of view. Acute Angle Less than 90 degree angles are referred to as acute angles. A smaller than 90° angle is created when two rays cross at a vertex or a point, creating an acute angle. A few instances of sharp angles are 20, 30, 45, and 60 degrees. PQR is an acute angle, as can be seen by looking at the diagram. Right Angle When the angle created by two rays is exactly 90 degrees, a right angle is created. It is also known as a 90-degree angle due to its unique definition. Angle AOB is referred to as a right angle since it has a 90 degree angle. A square between the two rays is always used to indicate a correct angle. Obtuse Angle Greater than 90 degr
