Hint: In order to know about right, acute and obtuse angles we should know about an angle. An angle is the space made between two intersecting lines at a common vertex. It is measured in degrees using a protractor.
Complete step by step solution:
Right Angle: An angle which when measured is exactly . In this angle, the two intersecting lines at are perpendicular to each other. Let’s see an example of an angle which is right angled, in which the square corner represents .
Acute Angle: An angle which when measured is less than . It can be any angle between and . Let’s see an example of an angle which is acute:
Obtuse angle: An angle which when measured is greater than . It can be any angle between and . Let’s see an example of an angle which is obtuse angled:
Note:
There are seven or more types of angles, in which the main angles are the right, acute and obtuse angles. Some of the other angles are:
1) Reflex angle: The angle which measures greater than and less than Or An angle between both of these degrees, is called Reflex angle.
2) Straight angle: An angle which is exactly .
3) Complete angle: An angle which covers total .
4) Complementary angles: When the sum of two acute angles give , or a right angle.
5) Supplementary angles: When the sum of two angles gives , or a straight angle.
