When two lines meet at a point, they form an angle at that point. An angle is actually the measurement of turn. It is measured in degrees e.g. 90° or 90 degree.
An angle gives an idea about the degree by which a line should be turned along its one end to overlap the other line.
There are different types of angles
1) Acute Angle: If the angle is less than 90° then it is called an acute angle.
2) Obtuse Angle: If the angle is greater than 90° then it is called an obtuse angle.
3) Right Angle: If the angle is equal to 90° then it is called a right angle.
4) Straight angle: If the angle is equal to 180° then it is called a straight angle.
