The edge length of an equilateral triangle is the measurement of one of its sides. In an equilateral triangle, all three sides are equal in length, making this measurement consistent across the entire triangle.
The calculator uses the formula:
Where:
Explanation: Since all sides are equal in an equilateral triangle, the semiperimeter is 1.5 times the edge length, making the edge length equal to 2/3 of the semiperimeter.
Details: Calculating the edge length is fundamental in geometry for determining other properties of the triangle such as area, height, perimeter, and for various construction and design applications.
Tips: Enter the semiperimeter value in meters. The value must be positive and greater than zero to get a valid result.
Q1: What is an equilateral triangle?
A: An equilateral triangle is a triangle with all three sides of equal length and all three angles equal to 60 degrees.
Q2: How is semiperimeter related to perimeter?
A: Semiperimeter is exactly half of the perimeter of the triangle.
Q3: Can this formula be used for other types of triangles?
A: No, this specific formula only applies to equilateral triangles where all sides are equal.
Q4: What are the units for edge length?
A: The edge length will have the same units as the semiperimeter input (typically meters or other length units).
Q5: How accurate is this calculation?
A: The calculation is mathematically exact for equilateral triangles, provided the semiperimeter value is accurate.
