Step 2-

Draw an arc with A as a centre which cuts AB at point C.

 

Step 3-

Draw another arc with same radius at c that cuts arc at point D.

 

Step 4-

Draw an arc with D as a centre taking same radius which cuts arc at E.

 

Step 5-

Draw an arc taking radius more than half of the arc DE from point D and E.

 

Step 6-

Mark the point of intersection as F. Join F to A. ∠FAB = 900
