Using ruler and compasses only, draw a right angle.

We have to draw a right angle using ruler and compasses only



We use the following algorithm for the construction


Steps of construction


STEP1: Draw a ray BC.


STEP2: With B as a centre, and taking convenient radius, draw an arc, intersecting the ray BC at point N.


STEP3: With N as a centre, and taking the same radius, draw an arc cutting the previous arc at M.


STEP4: With M as a centre, and the same radius, draw an arc cutting the arc drawn in STEP2 at L.


STEP5: With M as a centre, and the same radius draw an arc.


STEP6: With L as a centre, and the same radius, draw an arc cutting the arc drawn in STEP5 at A.


STEP7: Draw the ray BA.


ABC is a right angle.
