Question

how to construct 90° with compass?

Answer 1

draw a line segment AB. put your compass at point A and draw a arc. take compass to the point where arc intersects line segment AB without distributing it. draw a arc on the arc. the place where it intersects take the compass there and again form a arc on the arc. now bisect two arcs formed on it. draw a line from that point to point A. measure the angle, it would be 90.

Answer 2

Draw a line segment A B for any convenient measurement.

Take a suitable radius , with A as center draw a semicircle.

With the same radius with A as center cut an arc at P on the semicircle

With P as center cut another arc at Q on the same senicircle

With P and Q as centers draw each one arc above A B.

Let it cuts at R.

Join A and R.

Now A R is perpendicular to A B


we have constructed the angle of 90° hope it helps you don't forget to mark this answer as brainlist
