Triangle Median to Side A Calculator

The Triangle Median to Side A helps estimate cm in the context of math and geometry. It uses the specific input quantities Opposite side a cm, Other side b cm and Other side c cm rather than relying on a generic percentage or a hidden default. Enter measurements with the units displayed next to each field, and compare the calculated result with the worked example below. Sides must satisfy triangle inequality. It runs locally in the browser; no personal account or server calculation is required.

How to use this calculator

  1. Enter Opposite side a cm using the stated units, then confirm the number reflects your own situation.
  2. Enter Other side b cm using the stated units, then confirm the number reflects your own situation.
  3. Enter Other side c cm using the stated units, then confirm the number reflects your own situation.
  4. Review the displayed result and the stated limitation before using it in a real plan.

Triangle Median to Side A equation and assumptions

0.5*square root(2*Other side b cm*Other side b cm+2*Other side c cm*Other side c cm-Opposite side a cm*Opposite side a cm) → cm

  • The equation combines Opposite side a cm, Other side b cm, Other side c cm in the order shown and returns cm.
  • Sides must satisfy triangle inequality.

Worked examples

Worked example: Triangle Median to Side A

Try these values: Opposite side a cm = 5, Other side b cm = 6, Other side c cm = 7.

Evaluate 0.5*square root(2*Other side b cm*Other side b cm+2*Other side c cm*Other side c cm-Opposite side a cm*Opposite side a cm) with the example values.

The calculated result is approximately 6.0208 cm. Change the input values to explore a different scenario.

Understanding the result

The output is expressed in cm, using the input values you supplied.

Sides must satisfy triangle inequality.

Important notes
