The difference between a kite and a rhombus is that a kite does not always have four equal sides or two pairs of parallel sides like a rhombus. A kite is a four-sided shape that has two sets of adjacent sides that have equal lengths. All rhombuses and squares are also kites.
A kite is one type of four sided figure known as a quadrilateral. As with all quadrilaterals, the sum of its four angles is 360 degrees. The angles of a kite are equal at the points where the two pairs of adjacent sides meet. To calculate the area of a kite, the lengths of its two diagonals are multiplied together and the sum is divided by two.
