# equilateral triangle area and perimeter formula

a table of area formulas and perimeter formulas used to calculate the area and perimeter of two-dimensional geometrical shapes: square, rectangle. parallelogram, trapezoid (trapezium), triangle, rhombus, kite, regularTo find the area of an equilateral triangle, we can use the following formula If a segment splits an equilateral triangle into two regions with equal perimeters and with areas A1 and A2 , then[19]:p.151,J26.A regular tetrahedron is made of four equilateral triangles. Derivation of area formula. Triangle Calculator Area and Perimeter.Area of an equilateral triangle Area of an equilateral triangle When you know all three sides of a triangle, you can find the area using Herons Formula. Before we step into practical example, Let see the definitions and formulas behind the Area of an Equilateral Triangle.Within the next line, We are calculating the semi perimeter of an Equilateral Triangle using the following formula. In other words the equilateral triangle are equiangular or congruent to each other. Using below formulas area, perimeter semi perimeter and altitude can be find. Formula of Equilateral Triangle are as follows Finding the formula for the area of an equilateral triangle with side s. When you know all three sides of a triangle, you can find the area using Herons Formula. But in the case of equilateral triangles, where all three sides are the same length, there is a simpler formulaPerimeter / Area. A triangle is equilateral if and only if any three of the smaller triangles have either the same perimeter or the same inradius.[4]:Theorem 1.Substituting h into the area formula (1/2)ah gives the area formula for the equilateral triangle For example, area, height and radius of the inscribed or circumscribed circle. Step 4: If you know the radius of the inscribed equilateral triangle, a circle, then to calculate its perimeter, use the following formula: LMP 6 3 r, where: r - the radius of the inscribed circle. The formula is given below. Equilateral Triangle. s length of a side. See also.
