Question

1. Draw ZPOQ of measure 75° and find its line of symmetry.​

Answer 1

Here, we will draw

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 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, 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

∠BOA=75°
