Angle and measurements
An angle is a figure formed by two rays, known as sides of the angle sharing common point known as the vertex of the angle. Angle measurement has five types known as Acute angle(less than 90°), Right angle(90°), Obtuse angle(greater than 90° but less than 180°), Straight angle(180°) and Reflex angle(greater than 180°).
The addition is adding two numbers; subtraction, are the taking the number off.
