Find the perimeter of the frame.ĭraw any triangle. If the PERIMETER of the triangle is 11.2 feet, what is the length of the unknown side? (hint: draw a picture)Īn isosceles triangular frame has a measure of 72 meters on its legs and 18 meters on its base. The sides of the triangle are 5.2, 4.6, and x. The second stage is the calculation of the properties of the triangle from the available lengths of its three sides.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). The calculator solves the triangle specified by three of its properties.
