Use the compass to construct a perpendicular bisector of the line segment by scribing arcs from both endpoints above and below the line segment this will produce two intersecting arcs above and two intersecting arcs below the line segment Open the compass to span more than half the distance of the line segment See more information about triangles or more details on solving triangles.You can also construct the triangle using a straightedge and drawing compass:Ĭonstruct a line segment more than twice as long as the desired length of your triangle's leg Look also at our friend's collection of math problems and questions: Find the magnitudes of all angles of triangle A'B'C'.įind the third interior angle of the triangle ABC where: α = 48°, γ = 65°. The sizes of the angles of the triangle ABC are α = 35° and β = 48°. The triangles ABC and A'B'C' are similar to the similarity coefficient 2. Calculate the area of the triangle DKU if vertex U lies online LB. It is given square DBLK with side |BL|=13. How many cms do you measure on one of the same sides? The Triangle circumference with two identical sides is 117cm. How high does the upper end of the ladder reach? It is built so that its lower ends are 3.5 meters apart. Determine the lengths of the sides AB, AC triangle AĬan a rhombus have the same length, diagonal, and side? 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. 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?Ĭan it be a diagonal diamond twice longer than its side?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. 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. How many tulip bulbs does he need if he wants to plant 8 bulbs on a length of 1 m? The second stage is the calculation of the properties of the triangle from the available lengths of its three sides.Ī gardener plants one row of tulips around a triangular bed with sides of 5 m, 6 m, and 10 m.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.
