The second stage is the calculation of the properties of the triangle from the available lengths of its three sides.Īn isosceles triangular frame has a measure of 72 meters on its legs and 18 meters on its base.From the known height and angle, the adjacent side, etc., can be calculated.Ĭalculator use knowledge, e.g., formulas and relations like the Pythagorean theorem, Sine theorem, Cosine theorem, and Heron's formula. Calculator iterates until the triangle has calculated all three sides.įor example, the appropriate height is calculated from the given area of the triangle and the corresponding side. These are successively applied and combined, and the triangle parameters calculate. He gradually applies the knowledge base to the entered data, which is represented in particular by the relationships between individual triangle parameters. The calculator tries to calculate the sizes of three sides of the triangle from the entered data. The expert phase is different for different tasks.How does this calculator solve a triangle?The calculation of the general triangle has two phases: Usually by the length of three sides (SSS), side-angle-side, or angle-side-angle. Of course, our calculator solves triangles from combinations of main and derived properties such as area, perimeter, heights, medians, etc. The classic trigonometry problem is to specify three of these six characteristics and find the other three. Each triangle has six main characteristics: three sides a, b, c, and three angles (α, β, γ). Calculate the circumference and area of a trapezoid.The calculator solves the triangle specified by three of its properties. The arms have a length of 5 cm and height = 4.8 cm. The bases of the isosceles trapezoid are in the ratio of 5:3. The arm is 6cm long and 4cm high.Ĭalculate the volume and surface of a prism whose height is 16 cm, and the base is in the shape of a right triangle with 5cm and 12cm trunks and a 13cm diaphragm. How big is his circuit? c) Calculate the square's area if the diagonal's sĬalculate the area and perimeter of a regular nonagon if its radius of the inscribed circle is r = 10cmįind the area and perimeter of a square whose diagonal is 10 cm.Ĭalculate the area of an isosceles trapezoid whose bases are at a ratio of 5:3. b) A right isosceles triangle has an area of 40.5 square meters. Calculate the side sizes of the triangle and its height. The result is rounded to the nearest hundredth.Ĭalculate the length of diagonal u and height v of isosceles trapezoid ABCD, whose bases have lengths a = |AB| = 37 cm, c = |CD| = 29 cm and legs b = d = |BC| = |AD| = 28 cm.Ĭalculate the area and perimeter of an isosceles triangle ABC with base AB if a = 6 cm, c = 7 cm.Ī) The perimeter of the equilateral triangle ABC is 63 cm. Calculate the surface area of the prism.Ĭalculate the circumference and the area of the isosceles trapezoid if you know the size of the bases is 8 and 12 cm, and the size of the arms is 5 cm.Ĭalculate the perimeter and area of a rhombus whose diagonals are 39 cm and 51 cm long.Ĭalculate the area of an isosceles trapezoid ABCD, whose longer base measures 48 cm, the shorter base measures 3/4 of the longest base, and the leg of the trapezoid measures 2/3 of the longer base. Prism height is three times the height of the base triangle. The base of a vertical prism is an isosceles triangle whose base is 10 cm, and the arm is 13 cm long. Calculate the perimeter of this triangle. The base of the isosceles triangle is 17 cm area 416 cm². How could the surface area be calculated?Ĭalculate the area of an isosceles trapezoid whose bases are in the ratio of 4:3 leg b = 13 cm and height = 12 cm.Īn isosceles triangle with a base of 8 cm. We encourage you to watch this tutorial video on this math problem: video1 video2 Related math problems and questions:Ĭalculate the area of an isosceles right triangle whose perimeter is 252 cm.Ĭalculate the volume of a quadrilateral prism whose base is an isosceles trapezoid with bases 10 cm and 4 cm, 6 cm apart.
