How to construct angle 90 degrees ?
Will mark brainliest

We can construct a 90º angle either by bisecting a straight angle or using the following steps.

Step 1:  Draw the arm PA.

Step 2:  Place the point of the compass at P and draw an arc that cuts the arm at Q.

Step 3:  Place the point of the compass at Q and draw an arc of radius PQ that cuts the arc drawn in Step 2 at R.

Step 4:  With the point of the compass at R, draw an arc of radius PQ to cut the arc drawn in Step 2 at S.

Step 5:  With the point of the compass still at R, draw another arc of radius PQ near T as shown.

Step 6:  With the point of the compass at S, draw an arc of radius PQ to cut the arc drawn in step 5 at T.

Step 7:  Join T to P. The angle APT is 90º.

Hope this helps and good luck mate
