TYPES OF ANGLES
ANGLE
When two rays join together it makes an angle. The angle is denoted by degree ( ° ).
TYPES OF ANGLES
- Acute angle
- Right angle
- Obtuse angle
- Straight angle
- Reflex angle
ACUTE ANGLE
The angle is said to be acute which measures less than 90°.
RIGHT ANGLE

RIGHT ANGLE
When the angle measures exactly at 90° then it is said to be right angle.

OBTUSE ANGLE
The angle is said to be an obtuse when the angle measure is greater than 90°.

STRAIGHT ANGLE
When an angle is exactly at 180° then it is said to be a straight angle.

REFLEX ANGLE
The angle is said to be reflex when the measure an angle is greater than 180° and less than 360°.
COMPLEMENTARY ANGLE
When two angles are added and if the sum is 90° then it is said to be complementary angle.
