Question

With the help of protractor draw two angles

80 °

and

100 °

respectively. Now with the help of compass construct two more angles equal to

80 °

and

100 °

. Write the types of angles so drawn.

Accepted Answer

We have to draw the angle of value $80 °$ and $100 °$ using protractor and then draw same angle using compass.

First we will draw the angle of $100 °$ .

Draw a line segment $O R$ .

Place protractor to take measure of $80 °$ angle and mark it as $P$ .

Join point $O$ and $P$ to form angle $∠ R O P = 80 °$ .

Using suitable width of compass and taking $O$ as center draw an arc intersecting $O R$ at $A$ and $O P$ at $B$ .

Draw a line segment $Y Z$ using ruler.

Using earlier compass width draw an arc taking $Y$ as center intersecting $Y Z$ at $M$ .

Now using compass take width equal to $A B$ and taking $M$ as center cut the arc drawn in previous step at $N$ .

Join $Y N$ and draw a line segment $Y X$ .

Now we will draw the angle of $100 °$ .

Draw a line segment $E F$ .

Place protractor to take measure of $100 °$ angle and mark it as $D$ .

Join point $D$ and $80 °$ to form angle $∠ D E F = 100 °$ .

Using suitable width of compass and taking $E$ as centre draw an arc intersecting $E F$ at $T$ and $D E$ at $S$ .

Draw a line segment $U V$ using ruler.

Using earlier compass width draw an arc taking $U$ as centre intersecting $U V$ at $G$ .

Now using compass take width equal to $S T$ and taking $U$ as centre cut the arc drawn in previous step at $H$ .

Join $U H$ and draw a line segment $U W$ .

Hence, $∠ X Y Z = 80 °$ and $∠ W U V = 100 °$ .

With the help of protractor draw two angles $80 °$ and $100 °$ respectively. Now with the help of compass construct two more angles equal to $80 °$ and $100 °$ . Write the types of angles so drawn.
