2. Can we make a circle into
five equal parts using a
setsquare??
Using corners of a set
squares, we cannot make
such an angle at the
centre.

5. We need some other method to draw and measure
angles of different sizes.

6. What is the unit of measurement of lengths?
Millimetre , centimetre, metre and kilometre
Do you know the unit of measurement
of angles?
The measure of the angle is said to be degree( )

7.  We can make a circle into 360 equal pieces
 We get the measurement of each angle as 10
 The measurement of the above angle is 1 degree - 10
 Double of this angle is 2 degree - 20
 Triple of this angle is 3 degree - 30
 10 times of this angle is 10 degree - 100
 25 times of this angle is 25 degree - 250
 90 times of this angle is 90 degree - 900
 180 times of this angle is 180 degree - 180
