Find area of a kite calculator11/13/2023 ![]() Thus, the total height is Acos(θ/2) + sqrt(B² - A²sin²(θ/2)). This gives the rest of the height as sqrt(B² - A²sin²(θ/2)). To find the rest of the height, we use the Pythagorean theorem with B as the hypotenuse and Asin(θ/2) as one of the legs. The partial height of the kite is Acos(θ/2). Using trigonometry, we can deduce that the total width of the kite is 2Asin(θ/2). For the sake of example, let's say the known angle is θ which is the angle formed by two shorter sides with length A. Suppose you know the side lengths of the kite and one of either the top or bottom angles. ![]() Since there are two halves, the total area is ABsin(φ). Using the SAS formula for the area of a triangle, we can see that half of the kite has an area of (1/2)ABsin(φ). Suppose the two shorter sides of the kite have length A and the two longer sides have length B, and call the angle between two unequal sides φ. The triangular regions inside the rectangle and outside of the kite can be rearranged to form another kite of equal size and shape. The kite takes up exactly 1/2 of the area of the rectangle. To see why this is so, imagine drawing a rectangle around the kite with the longer side parallel to the kite's height, the shorter side parallel to the kite's width, and the points of the kite on the rectangle's perimeter. If we represent the two measurements by W and H respectively, then the area of the kite is (1/2)WH. The width of a kite is the shorter distance between opposite points and the height is the greater distance between the other pair of opposite points. ![]() Each formula is explained below and references the diagram below the calculator on the left. Calculator - find pentagon area, given square area and triangle area Find area. There are several formulas for computing the area of a kite depending on which measurements are known. kite, rhombus and a variety of compound shapes. (If equal sides are opposite to one another, the figure is a parallelogram.) In a kite, the sides of equal length are adjacent to one another. There are numerous other proofs ranging from algebraic and geometric proofs to proofs using differentials, but the above are two of the simplest versions.Kite Area Calculator Fill in either WH, ABθ, ABφ, or ABλ W =Ī kite is a quadrilateral with two pairs of sides that have equal length. Which is again, the Pythagorean equation. Since the larger square has sides c and area c 2, the above can be rewritten as: ![]() The area of the larger square must then equal the sum of the areas of the four triangles and the smaller square such that: (b - a) 2 + 4 The four triangles with area abĪlso form a larger square with sides of length c. In the second orientation shown in the figure, ii, the four copies of the same triangle are arranged such that they form an enclosed square with sides of length b - a, and area (b - a) 2. The sum of the area of these four triangles and the smaller square must equal the area of the larger square such that: (b + a) 2 = c 2 + 4 This results in the formation of a larger square with sides of length b + a, and area of (b + a) 2.

Assume 5 in, 13 in, and 30 for the first diagonal, the second one, and the angle between them, respectively. In the first one, i, the four copies of the same triangle are arranged around a square with sides c. Enter the given values to the right boxes. In the figure above, there are two orientations of copies of right triangles used to form a smaller and larger square, labeled i and ii, that depict two algebraic proofs of the Pythagorean theorem. There are a multitude of proofs for the Pythagorean theorem, possibly even the greatest number of any mathematical theorem. If the angle between the other sides is a right angle, the law of cosines reduces to the Pythagorean equation. The law of cosines is a generalization of the Pythagorean theorem that can be used to determine the length of any side of a triangle if the lengths and angles of the other two sides of the triangle are known. It follows that the length of a and b can also be determined if the lengths of the other two sides are known using the following relationships: This relationship is useful because if two sides of a right triangle are known, the Pythagorean theorem can be used to determine the length of the third side. This is known as the Pythagorean equation, named after the ancient Greek thinker Pythagoras. In other words, given that the longest side c = the hypotenuse, and a and b = the other sides of the triangle: Given a right triangle, which is a triangle in which one of the angles is 90°, the Pythagorean theorem states that the area of the square formed by the longest side of the right triangle (the hypotenuse) is equal to the sum of the area of the squares formed by the other two sides of the right triangle: The Pythagorean Theorem, also known as Pythagoras' theorem, is a fundamental relation between the three sides of a right triangle.
