    1. First find the midpoints of the diagonals. So let their intersection point be O, then find the length of AO and BO

    2. The diagonals of a rhombus intersect at 90 degree angles, so use Pythagorean Theorem to find the length of AB

    How do you find the length of AO and BO?

    AO and BO represent half the lengths of their respective diagonals.

    AO is half the length of AC BO is half the length of BD

    3. Draw the line segment PQ 4. Assume P and Q are the midpoints of AO and BO 5. Find PO and QO. 6. Use Pythagorean Theorem once more to find PQ.
