Question

Draw the following:
The square READ with $RE=5.1$ cm.

Answer 1

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

First draw a line segment with a measure of $5.1$ cm. This is line $RE=5.1$ cm.

Then using protractor mark ${90}^0$ and again mark $5.1$ cm 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.
