# Q1.    Draw $\angle$POQ of measure 75° and find its line of symmetry.

D Divya Prakash Singh

Here, we will draw $75^{\circ}$ using a protractor.

We follow these steps:

1. Draw a ray OA.

2. Place the centre of the protractor on point O, and coincide line OA and Protractor line

3. Mark point B on 75 degrees.

4. Join OB

Therefore $\angle AOB = 75^{\circ}$

Now, we need to find its line of symmetry

that is, we need to find its bisector.

We follow these steps

1. Mark points C and D where the arc intersects OA and OB

2. Now, taking C and D as centres and with the radius more than $\frac{1}{2}CD$, draw arcs to intersects each other.

3. Let them intersects at point E.

4. Join O and E.

Therefore OE is the line of symmetry of $\angle BOA = 75^{\circ}$
