Let’s draw a square DEAR where DE = 5.6 cm.

It is given that,

DE = 5.6 cm

To do: Draw a square DEAR.

Required: Paper, pencil, and ruler and a compass.

Steps:

Note that, a square is a type of quadrilateral that has 4 equal sides and each angle making 90°.

1. Draw a line DE = 5.6 cm on a paper using a ruler.

2. Now, we need to construct 90° angle at vertex D as well as E (since, this is a square). So, keep one end of the compass at D, and draw an arc of any radius smaller than DE, say, 2 cm, cutting the line DE at Q.

3. Keeping one end of compass at Q, draw an arc or circle of the same radius cutting the arc drawn in step 2 at S.

4. Taking S as centre, draw an arc or circle of same radius cutting the previous arc at T.

5. Now, taking T as centre draw an arc or circle of same radius cutting the previous arc at Z.

6. Join DZ and extend it to R, such that, DR = 5.6 cm. (since, DEAR is a square)

Thus, we have got ∠EDR = 90°.

7. Similarly, taking E as centre and repeat the steps.

Thus, we have got ∠DEA = 90°.

8. Now, join AR.

Now, measure the angles that should be 90° each.

Thus, we have got the square DEAR.
