Formula
- Triangle Altitude (Height) Calculator calculates its result from Base, Area, Side a (optional), Side b (optional), Side c (optional). It uses the formula Altitude to base = 2×Area/base; Heron's: Area = √(s(s−a)(s−b)(s−c)); ha = 2×Area/a. Change any input to recalculate the result instantly.
- The main inputs are Base, Area, Side a, Side b, Side c. Enter them in the units and format shown in the calculator.
- Keep comparable quantities in compatible units whenever the formula combines or compares them.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Triangle Altitude (Height)
- Base: 8
- Area: 20
- Side a: 5 optional
- Side b: 6 optional
- Side c: 7 optional
Using Base = 8, Area = 20, Side a (optional) = 5, Side b (optional) = 6, Side c (optional) = 7, the calculated result is 15.
