Equilateral Triangle Calculator Calculations at an equilateral triangle or regular trigon. Calculate the length of height = bisector = median if given side Calculate the height of an equilateral triangle - Calculator Online Home List of all formulas of the site If you have any 1 known you can find the other 4 unknowns. This online calculator calculates characteristics of the equilateral triangle: the length of the sides, the area, the perimeter, the radius of the circumscribed circle, the radius of the inscribed circle, the altitude (height) from single known value. Enter one value and choose the number of decimal places. That is, if you know either the length of the sides, the area of the equilateral triangle, the perimeter of the triangle, the radius of the circumscribed circle, the radius of the inscribed circle or the altitude (height) of the triangle, you can find all other quantities. Perimeter of Equilateral Triangle: P = 3a, Semiperimeter of Equilateral Triangle: s = 3a / 2, Area of Equilateral Triangle: K = (1/4) * √3 * a, Angles of Equilateral Triangle: A = B = C = 60°, a = √ [ (4 / √3) * K ] = 2 * √ [ K / √3 ]. Area of a rhombus. By the way, note that the apothem, or the height of the center from each side also is, Everyone who receives the link will be able to view this calculation, Copyright © PlanetCalc Version:
*Length units are for your reference only since the value of the resulting lengths will always be the same no matter what the units are. EN: trapezoid-perimeter-area-calculator menu. So if you know the length of a side = a, or the perimeter = P, or the semiperimeter = s, or the area = K, or the altitude = Calculator solve the triangle specified by coordinates of three vertices in the plane (or in 3D space). The related formulas are listed under the calculator for reference. Thanks for the feedback.

From Contact: aj@ajdesigner.com. Uses Heron's formula and trigonometric functions to calculate area and other properties of a given triangle. To this, the equilateral triangle is rotationally symmetric at a rotation of 120°or multiples of this. Because of the regular nature of the equilateral triangle, we can determine many of its quantities from a single known value.
Use symbols: a, h, T, p, r, R. You have entered side a. Equilateral triangle. Equilateral triangle formulas. It is also a regular polygon, so it is also referred to as a regular triangle.

Precalculus Mathematics. To these, the equilateral triangle is axially symmetric. Equilateral triangle calculator This equilateral triangle calculator calculates any equilateral triangle by entering one of its properties (except angles because α = β = γ = 60°). Area of a triangle given sides and angle. P = perimeter Cite this content, page or calculator as: Furey, Edward "Equilateral Triangles Calculator"; CalculatorSoup, square meter). An equilateral triangle is a triangle in which all three sides are equal, so internal angles are 60° each. a = side a Area of a square. These values are connected by these formulas below: There are some shortcut formulas where you can find values directly from the altitude (height) of the triangle if you know it without first computing the length of the side. c = side c h = ha = hb = hc.
