Look also at our friend's collection of math problems and questions: Find a suitable way to determįind the area of a triangle with a base of 7 mm and a height of 10 mm. 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 original height of the tree. The top of the tree touches the ground at a distance of 5 meters from the trunk. The tree is broken at 4 meters above the ground. Determine the magnitudes of all angles of triangle A'B'C '. The angles of the triangle ABC are alpha = 35° and beta = 48°. The triangles ABC and A'B'C 'are similar, with a similarity coefficient of 2. Find the number of all triangles whose vertices lie at given points on different sides. (Sketch, analysis, notation of construction, construction)Īn equilateral triangle A, B, and C on each of its inner sides lies N=13 points. Determine the lengths of the sides AB, AC triangle AĬonstruct the triangle ABC if you know: the size of the side AC is 6 cm, the size of the angle ACB is 60°, and the distance of the center of gravity T from the vertex A is 4 cm. KLM is an isosceles triangle with a right angle at point K. Points L and M split the AC side into three equal lines. In a triangle ABC with the side BC of length 2 cm. (a) Measure the distance of point S from all three vertices (b) Draw the axis of the third party.Ĭonstruct triangle ABC in which |AB|=5cm, |AC|=6cm and |BC|=9cm 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 long is the height of this right triangle?Ī triangle has vertices at (4, 5), (-3, 2), and (-2, 5). The right triangle ABC has a hypotenuse c 9 cm long and a part of the hypotenuse cb = 3 cm. Find the perimeter of the frame.Ĭan it be a diagonal diamond twice longer than its side? 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.
