Scalene Triangle Calculator
The scalene triangle calculator will answer all the important questions regarding the triangles of unequal sides.
What Scalene Triangle Calculator does
A scalene triangle calculator determines all key properties of a triangle with three unequal sides. Users input the three side lengths, and the tool outputs the perimeter, semi-perimeter, area, and the three interior angles. It also computes the height corresponding to each side, providing a complete geometric profile of the shape. The results are derived from standard trigonometric formulas, allowing users to fully define the triangle from its side lengths alone. This makes it a practical resource for anyone needing accurate measurements of irregular triangles without manual calculation errors. The Omni Calculator version stands out for its clean, side-by-side input fields and immediate output display. The interface presents side lengths (a, b, c) and corresponding heights (h_a, h_b, h_c) alongside angle measures (α, β, γ) and area/perimeter values in a single scroll. Inline explanations appear directly beneath each input, clarifying what each value represents. A “Special triangle?” toggle and a “Share result” link add modest interactive extras. Compared to generic calculators, the layout avoids clutter by grouping related outputs—angles with angles, heights with heights—making it easy to cross-reference measurements at a glance.

Best for
Students, educators, and professionals in mathematics, architecture, or engineering who need quick, accurate measurements of scalene triangles without manual trigonometry.
Limitations
- Requires valid side lengths that satisfy the triangle inequality theorem
- Input values must be positive numbers; non-numeric or zero entries will not produce a triangle
- Results are mathematical estimates based on provided side lengths and do not account for physical material properties or drawing scale
Scalene Triangle Calculator FAQ
- Can I use this calculator if I only know two sides and one angle?
- No, the tool requires all three side lengths to compute the triangle's properties. If you have two sides and an angle, you would need a different calculator that supports that specific input combination.
- What happens if I enter side lengths that cannot form a triangle?
- The calculator will not produce a valid result. For a triangle to exist, the sum of any two sides must be greater than the length of the third side; entering lengths that violate this rule will result in an error or no output.
- Does the tool show the triangle's height from every vertex?
- Yes, it calculates the height corresponding to each of the three sides (h_a, h_b, h_c), which represents the perpendicular distance from the opposite vertex to that side.
- Can I share the calculated results with others?
- Yes, the interface includes a 'Share result' link that allows you to generate a shareable link or copy the output to send to colleagues or classmates.
