  1. 11.4 The Area Of a Kite Objective: After studying this section you will be able to find the areas of kites

  2. Remember When We Learned Properties of Special Quadrilaterals? 1. In a kite, the diagonals are perpendicular. 2. The longer diagonal bisects the shorter diagonal. This means the kite can be divided into 2 isosceles triangles with a common base…so its area will equal the sum of the areas of the two triangles.

  3. Let’s A E E B B D D C

  4. But Wait! Did you notice BD and AC are the diagonals of the kite?! (We just proved the formula for area of a kite…no big deal!) Theorem The area of a kite equals half the product of its diagonals. where d1 is the length of one diagonal, and d2 is the length of the other diagonal

  5. Just a Note… This formula can be applied to any kite, including the special cases of a rhombus and a square d2 d1

  6. Example #1 Find the area of a kite with diagonals 9 and 14

  7. Example #2 Find the area of a rhombus whose perimeter is 20 and whose longer diagonal is 8.
