Step-by-step explanation:

Step 1 : Draw a line Segment BA using ruler

Step 2 : Draw an angle of 120° at A on BA and mark other end as C

Step 3 : Using compass taking A as center Draw arc such that it intersect AB & AC at P & Q

Step 4 : Taking some width of compass Draw an arc taking P as center

Step 5 : Keeping same width of compass as in step 4 , draw arc taking Q as center Such that it intersect arc drawn in step 5 at R

Step 6 : Join AR & Extend

Now repeat Step from 3 to 6 taking AR & AC ( instead of AB & AC)

and get line AM

∠BAM = 90°
