| Square ABCD;

АС and ВD – square diagonals;

AC = 16 cm.

Let’s find the length of BО.

1) In a square, the diagonals are equal.

Hence, AC = BD = 16 cm.

2) Since longing) is the intersection point of the diagonals in the square, then BO is equal to half of the BD diagonal.

3) Divide the diagonal BD by 2 and find BO.

BO = BD / 2 = 16 cm / 2 = 8 cm.

Answer: BО = 8 cm.
