Triangle Area Calculator
Calculate triangle area from base and height with the formula area = base×height/2. Example: base 10, height 6 → area 30. Browser-only geometry process for homework and quick checks.
How it works
Choose base-height mode, enter base and perpendicular height, then calculate.
Formula
A = (b×h)/2. Notes:
- Height must be perpendicular to the chosen base.
- Other modes are not included in this page.
- Pair with circle / volume tools.
Example
Example: base 10, height 6 → 30.
When to use it
- Geometry homework.
- Quick area sketch.
- Compare related shape tools.
