Book Free DemoWhen two rays diverge from a common point, they are called Angles. The rays which form an angle are called the angle arms, and the common point is called the angle vertex.
Types of angles
We may summarize them up as follows:
Acute angle: Angles measuring lesser than 90° are called acute angles, but the measurement can neither be 0 nor a negative value.
Right angle: An angle measuring exactly 90° is a right angle.
Obtuse angle: An angle greater than 90° is considered an obtuse angle.
Straight angle: A straight angle is called an angle whose measure is exactly 180°.
Reflex angle: An angle measuring greater than 180° and lesser than 360° is referred to as a reflex angle.
