If CD =4.5 cm; find the length of AB.

In the trapezium ABCD, AD || BC and the diagonals intersect at O. Prove that.

State true or false:

In quadrilateral ABCD,

A D = B C

and the diagonals

A C

B D

intersect at point

O

\frac{O C}{O A} = \frac{O D}{O B} = \frac{1}{3}

, then the quadrilateral
