What is the length of the diagonal of a square whose sides measure 8 cm.

Given :

To Find :

Using Formula :

Here is the formula to find the side of square if diagonal is given :

Where :

Solution :

Substituting the given value in the required formula :

Hence, the length of the side of square is 5.6 cm.

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
