1. What is the Height of Equilateral Triangle?

The height of an equilateral triangle is the perpendicular distance from any vertex to the opposite side. In an equilateral triangle, all three sides are equal and all three angles are 60 degrees, making the height a fundamental measurement for various geometric calculations.

2. How Does the Calculator Work?

The calculator uses the height formula derived from the area:

\[ h = \frac{\sqrt{3}}{2} \times \sqrt{\frac{4 \times A}{\sqrt{3}}} \]

Where:

\( h \) — Height of the equilateral triangle (meters)
\( A \) — Area of the equilateral triangle (square meters)
\( \sqrt{3} \) — Square root of 3 (approximately 1.732)

Explanation: This formula calculates the height of an equilateral triangle when the area is known, using the mathematical relationship between area, side length, and height.

3. Importance of Height Calculation

Details: Calculating the height of an equilateral triangle is essential in geometry, engineering, architecture, and various design applications where precise measurements and proportions are required.

4. Using the Calculator

Tips: Enter the area of the equilateral triangle in square meters. The value must be positive and greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

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 the height related to the side length?
A: In an equilateral triangle, the height can be calculated from the side length (s) using the formula: h = (√3/2) × s

Q3: Can I calculate the side length from the height?
A: Yes, the side length can be calculated from the height using the formula: s = (2/√3) × h

Q4: What are practical applications of this calculation?
A: This calculation is used in construction, engineering design, computer graphics, and any field requiring geometric precision with equilateral triangles.

Q5: Why is the formula structured this way?
A: The formula is derived from the relationship between area, side length, and height in an equilateral triangle, using algebraic manipulation to solve for height given the area.
