There's a lot going on with this kite. So, do some reading here: http://www.coolmath.com/reference/kites.html A kite is a quadrilateral that has two sets of adjacent sides that are the same length (congruent) and one set of opposites angles that are congruent. The area of a kite is one-half the product of its diagonals. In the problem, the diagonals are not given. Use the 45-45-90 theorem to find the length of one diagonal along with one of the kite properties. The marked up diagram is attached. A = (1/2)* 18 * 15 = ? for the area @Alexwildeux
