ABCD is a rectangle whose diagonals AC and BD meet at O. The diagonals make OA = OB = OC = OD.
If diagonal AC = 26 cm, find the length of OB (in cm).

Question

ABCD is a rectangle whose diagonals AC and BD meet at O. The diagonals make OA = OB = OC = OD. If diagonal AC = 26 cm, find the length of OB (in cm).

Accepted Answer

13. Diagonals of a rectangle are equal and bisect each other, so OB = AC/2 = 26/2 = 13 cm.
