Question

Construct a square of side 4 cm.

Answer 1

We know that, all sides of a square are equal and each side is perpendicular to adjacent side.

So, AB = BC = CD = DA = 4 cm

Steps of construction:

Step I: Draw `bar(AB)` = 4 cm.

Step II: At B, draw `bar(BX)` that is ∠ABX = 90°.

Step III: From `bar(BX)`, cut-off BC = 4 cm.

Step IV: With centre C and radius = 4 cm, draw an arc.

Step V: With centre A and radius = 4 cm, draw another arc to intersect the previous arc at D.

Step VI: Join DA and CD.

Hence, ABCD is the required square.
