Look also at our friend's collection of math problems and questions: Calculate the perimeter of the triangle.Ĭalculate the length of a side of the equilateral triangle with an area of 50cm². The ABC right triangle with a right angle at C is side a=29 and height v=17. Find a suitable way to determĬan a rhombus have the same length, diagonal, and side? The farmer had a fenced field, so he knew the lengths of the sides: 119, 111, and 90 meters. The required amount depends on the seed area. The farmer would like to first seed his small field. Calculate the area of the triangle DKU if vertex U lies online LB. It is given square DBLK with side |BL|=13.

How long is the height of this right triangle?Ĭonstruct triangle ABC in which |AB|=5cm, |AC|=6cm and |BC|=9cmĬalculate the area of a right triangle whose legs have a length of 6.2 cm and 9.8 cm. The right triangle ABC has a hypotenuse c 9 cm long and a part of the hypotenuse cb = 3 cm. (a) Measure the distance of point S from all three vertices (b) Draw the axis of the third party. What are the coordinates of the vertices of the image after the translation (x, y) arrow-right (x + 3, y - 5)?Ĭalculate the area of the ABE triangle AB = 38mm and height E = 42mm Ps: please try a quick calculationĭraw any triangle. How many tulip bulbs does he need if he wants to plant 8 bulbs on a length of 1 m?Ĭan it be a diagonal diamond twice longer than its side?Ī triangle has vertices at (4, 5), (-3, 2), and (-2, 5). Find the perimeter of the frame.Ī gardener plants one row of tulips around a triangular bed with sides of 5 m, 6 m, and 10 m. 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.

The calculator uses use knowledge, e.g., formulas and relations like the Pythagorean theorem, Sine theorem, Cosine theorem, and Heron's formula. From the known height and angle, the adjacent side, etc., can be calculated.

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 are calculated. 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.
