Draw angles of the measure given below:

$40°, 90°, 135°$

Now check the picture given below.

Is there any angle drawn by you which appears to be equal to the angle given above? What is the measure of the angle?

Draw angle ${180}^{°}$ using protractor.

Using a ruler and compass, construct angles of the following measures.

${60}^o$

Using a ruler and compass, construct angles of the following measures.

$30°$

Construct angle ${60}^{\circ }$ using protractor and a ruler.

Draw an angle equal to $\angle AOB$, given in the figure below.

Draw an angle $\angle PQR={110}^o$ with the help of a protractor. Now draw $\angle ABC=\angle PQR$ using a ruler and compass.
