ObjectivesAt the end of this module you will be able to-To know about definition of angles.To know about there types.To draw and identify different angles.Lets start module2

Angles A figure formed by two rays with a common initial point is called an angle.It is denoted by >. In a figure, an angle is formed by rays BA & BC. BA and BC are the arms of the angles and the common initial point B is called the vertex.Lets answer some questionsanswer 3

Lets answer some questionsanswer 4Types of anglesDefinition When two arms of an angle overlap each other , the angle formed between is zero angle.An angle which measures between 0 and 90 is called acute angleAn angle which measure 90 is called a right angle.An angle which measure more than 90 but less than 180 is called a obtuse angle.An angle which measure 180 is called a straight angle.An angle which measure more than 180 but less than 360 is called a reflex angle.When the sum of two angle are 90 is known as complementary angle.When the sum of two angles are 180 is known as supplementary angle.An angles which measure is 360 is known as complete angle.
