Equilateral Triangle Calculator: Find Area, Perimeter, and Height Instantly

Calculate Equilateral Triangle Properties

Discover the properties of an equilateral triangle effortlessly! Our intuitive online calculator helps you find the area, perimeter, and height by simply inputting the side length. Ideal for geometry students, engineers, and DIY enthusiasts looking for accurate results.

Formula:

An equilateral triangle has three equal sides and three equal angles (60°). If 's' is the side length:

  • Area (A) = (√3 / 4) × s²
  • Perimeter (P) = 3 × s
  • Height (h) = (√3 / 2) × s
Where s = side length of the equilateral triangle.
