Construction of 90 Degree Angle with the help of Compass

45 Degree Angle 60 Degree Angle 90 Degree Angle 120 Degree Angle 135 Degree Angle
150 Degree Angle

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 cuts line 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.
