Answer» STEPS OF CONSTRUCTION:- 1)Draw a ray OA . 2)With O as centre and any suitable radius draw an arc cutting OA at B . 3)With B as centre and same radius cut the previous drawn. arc at C and then with C as centre and radius cut the arc at D. 4(With C as centre and radius more than half Cd draw an arc . 5)With D as centre and same radius draw another arc to cut the previous arc at E. 6=)Join OE ,then angle AOE ==90°. 7))Draw the bisector OF of Angle AOE ,then Angle AOF =45°. Justify...... By construction.Angle AOE ==90° and OF is the bisector of Angle AoE So, Angle =1/2/_AOE =1/2×90°==45° thanks

STEPS OF CONSTRUCTION:-

1)Draw a ray OA .

2)With O as centre and any suitable radius draw an arc cutting OA at B .

3)With B as centre and same radius cut the previous drawn. arc at C and then with C as centre and radius cut the arc at D.

4(With C as centre and radius more than half Cd draw an arc .

5)With D as centre and same radius draw another arc to cut the previous arc at E.

6=)Join OE ,then angle AOE ==90°.

7))Draw the bisector OF of Angle AOE ,then Angle AOF =45°.

Justify......

By construction.Angle AOE ==90° and OF is the bisector of Angle AoE

So, Angle =1/2/_AOE =1/2×90°==45°

thanks
