Question

Who to cnstract 90 deegre

Answer 1

Follow the following step to construct 90 Degree Angle 

1). Use ruler and draw a Line segment OB of any convenient length. (as shown below) 

 

2). Now use compass and open it to any convenient radius. And with O as center , draw an arc which cutsline segment OB at X. (as shown below) 

 

3). Again use compass and opened to the same radius (as of step 2). And with X as center , draw an arc which cuts first arc at D . (as shown below) 

 

4). Again use compass and opened to the same radius (as of step 2). And with D as center , draw another arc which cuts first arc at C . (as shown below) 

 

5). Again use compass and opened to the same radius (as of step 2). And With C & D as center , draw two arc which cuts each other at E . (as shown below)

 

6). Join OE and extent it to A . (as shown below) 

 

7). Above formed angle AOB = 90 Degree. 

Answer 2

first draw a line then take a radius and draw an arc and with same radius make 60 and 120 degree. angle between the two of the angle is 90 degree
