Question 190
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 $\overline{AB}=4cm$
Step II At B, draw $\overline{BX}$ such that $\angle ABX={90}^{\circ }$.
Step III From $\overline{BX}$, 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.
Thus, ABCD is the required square.
