![]() ![]() The area of the kite equals 20 x 15 x sin150°, which equals 300 x sin150°, or 150 square inches. For instance, say you have a kite with two sides that are 20 and 15 inches long, with an angle of 150° between them. Rectangle: A rectangle is a quadrilateral with four right angles. Quadrilateral: A quadrilateral is a closed figure with four sides and four vertices. Parallelogram: A parallelogram is a quadrilateral with two pairs of parallel sides. To do this, use the formula A = a x b x sinC, where a and b are the lengths of the sides and C is the angle between them. Kite: A kite is a quadrilateral with distinct adjacent congruent sides. If you don’t know the lengths of the diagonals, you can find the area of the kite using the lengths of two non-congruent sides (that is, two sides that are not of the same length) and the size of the angle between them. Before talking about the types of quadrilaterals, let us recall what a quadrilateral is. For example, if you have a kite with a diagonal of 7 inches and another diagonal of 10 inches, the area of the kite would equal (7 x 10)/2, or 35 square inches. If you know the lengths of these diagonals, you can plug them into the formula A (area) = xy/2, where x and y are the two diagonals. A pair of diagonally opposite angles of a kite are said to be to the right of the longer diagonal. of a kite is half the product of its diagonals. This is the exact shape that home plate and. The reason your method wont work is because you cannot divide an irregular polygon equally. You can easily find the area of a kite if you know the lengths of the diagonals, or the two lines that connect each of the adjacent vertices (corners) of the kite. The sides AC and BC are equal and AD and BD are equal which form the two isosceles triangles. In Euclidean geometry, a kite is a quadrilateral whose four sides can be grouped into two pairs of equal length sides that are adjacent to each other. Simply add the three known angles together and subtract that from 360, because all the angles in a quadrilateral add up to 360.
