Triangle Median Length Calculator

Quick answer

This calculator computes the triangle median length: exact formula mₐ = ½√(2b²+2c²−a²), worked example a = 10, b = 8, c = 6 cm → m_a = 5 cm.

How the triangle median length Calculator Works

m_a = ½·√(2b² + 2c² − a²)

The calculator applies the exact formula m_a = ½·√(2b² + 2c² − a²). Worked example: a = 10, b = 8, c = 6 cm → m_a = 5 cm. Keep every input in one unit system and the result follows in length units (m, ft, cm); full precision is kept until the final rounding. Angles in radians pair with s = rθ; convert degrees with × π/180.

  1. 1

    Enter the measurements

    Type the values required by the formula for triangle median length.

  2. 2

    Check the units

    One unit system throughout — cm, m, ft or in.

  3. 3

    Read the result

    The calculator substitutes, evaluates and rounds only at the end.

Tips

  • 1

    Keep angles in radians for s = rθ formulas

  • 2

    1 rad = 57.2958°; degrees × π/180 = radians

  • 3

    Unroll curved paths into straight segments to sanity-check

Common Mistakes

  • Degrees entered where radians are required

  • Using the chord length as the arc length

  • Rounding π too early in chain calculations
