What SSA Triangle Calculator does
SSA (Side-Side-Angle) ambiguous case: two sides and a non-included angle are known. The tool calculates the missing side or angle using the Law of Sines, handling the ambiguous case (0, 1, or 2 possible triangles) and displaying step-by-step calculations and the resulting triangle geometry. It supports solving for sides, angles, area, and perimeter given sufficient initial data. } } , { "type": "text", "text": "The tool calculates missing sides or angles in a triangle given sufficient initial data (two angles and a side, or two sides and a non-included angle). It supports scenarios where you know two angles and one side (AAS or ASA), two sides and a non-included angle (SSA), or all three sides (SSS). The calculator determines unknown side lengths or angle measures, checks triangle validity (triangle inequality), and handles the ambiguous case (SSA) where two different triangles may satisfy the given conditions. It provides step-by-step solutions showing the Law of Sines application, calculates triangle area, and determines if zero, one, or two triangles are possible based on the given dimensions. The tool handles cases where no triangle exists, one unique triangle exists, or two possible triangles exist (the ambiguous case).

Best for
Finding missing sides or angles in a triangle when some sides and angles are known. Especially useful for SSA (Side-Side-Angle) cases where the ambiguous case may produce two possible triangles.
Limitations
- Requires at least one side length and one angle to solve the triangle.
- Angles must be in degrees or radians as specified; ensure consistent units.
SSA Triangle Calculator FAQ
- Can I use this for non-right triangles?
- Yes, this calculator handles any triangle shape using the Law of Sines and Law of Cosines.
- What if I only know two sides and need the angle?
- Use the Law of Cosines to find the missing angle, then use the Law of Sines to find the remaining sides or angles.
- Can I use this for 3D geometry?
- No, this calculator is for 2D planar triangles only.
