# altitude of equilateral triangle formula

The equilateral triangle is the only acute triangle that is similar to its orthic triangle (with vertices at the feet of the altitudes) (the heptagonal triangle being the only obtuse one). Math Geometry Physics Force Fluid Mechanics Finance Loan Calculator. Draw the altitude from B forming BD. Let a be the length of the sides, A - the area of the triangle, p the perimeter, R - the radius of the circumscribed circle, r - the radius of the inscribed circle, h - the altitude (height) from any side.. They also have three equal altitudes; Is the height of an equilateral triangle equal to its side length. I’m on an equilateral-triangle-questions streak lately lmao. The amount of space occupied in a two dimensional plane of an equilateral triangle is called the area of equiangular or equilateral triangle. Similarly, the altitude can be calculated for an equilateral using the same method. For an equilateral triangle, all angles are equal to 60°. Altitude of an Equilateral Triangle Formula. We can find the altitude of the equilateral triangle, whose sides is $a,$ using the formula $h=\dfrac{a\sqrt{3}}{3}$ Equilateral Triangle. The formula is given below: Area of an Equilateral Triangle. Equilateral triangle formulas. Area of Equilateral Triangle. The altitude of a triangle, or height, is a line from a vertex to the opposite side, that is perpendicular to that side.It can also be understood as the distance from one side to the opposite vertex. Triangle Equations Formulas Calculator Mathematics - Geometry. Therefore, perimeter= AB+BC+CA. Hence, Altitude of an equilateral triangle formula= h = √(3⁄2) × s (Solved examples will be updated soon) Quiz Time: Find the altitude for the equilateral triangle when its equal sides are given as 10cm. No It is easy to imagine with everything being equal that the height, and the side length would be equal, but they are not. The formula for Area of an Equilateral Triangle. Find the altitude of a triangle if its area is 120sqcm and base is 6 cm. Let suppose ∆ABC is an equilateral triangle whose all the sides are equal and each angle measures 60°.
