Answer 1

ANSWER

1. We know sides of square are equal. Thus RE=EA=AD=RD=5.1 cm.

First draw a line segment, then measure 5.1 cm in rounder and mark the arcs. This is line RE=5.1 cm.

Then using protactor mark 90 degree and again mark 5.1 cm in on that line segment. This is EA.

Again mark 5.1 cm in protactor and make line AD.

At last join points D and R.

This completes a square.
