Question

Construct and write steps of construction of angle measuring 90 degrees

Answer 1

1). Take a straight line segment

2). make an arc of 180 using compass

3) with same opening of compass bisect the arc in two parts which two measures 60 and 120

4). bisect the angle between 60 and 120

5). produce the line from particular point bisecting the angle of 60 and 120

6). you will get angle of 90

hope this will surely help you

Answer 2

Draw a line segment of any length
Draw a semi circle from at initial point of line segment with the help of compass
Don't spoil the compass which you have measure to make semi circle
From right side of semi circle draw a arc to cut semi circle at 60 degree
Again keep needle on 60 degree point and cut the semi circle at 120 degree by making an arc
Keep needle on 60 degree and draw an arc above the semi circle
Again keep needle on 120 degree and draw an arc which touch the arc made above
The point which at cut both above arc meet the initial point of line segment to that point

Measure the angle with protactor you find it is 90 degree
