Triangle Solver in your browser

By Team Edtoolkits · Study & learning

Solve a triangle from any three values (sides or angles) with the sine and cosine rules, including the ambiguous SSA case, with a drawing, area and working.

Use the guide alongside the working tool.

Get started

Fill in any three values: sides a, b, c (opposite angles A, B, C) and angles in degrees. Leave the rest blank.

Adjust and explore

Read the missing sides and angles, the area, and the drawing. If two triangles fit, both are shown.

Save and share

Follow the working, then copy it or share a link.

Privacy and limits

Needs exactly three values including at least one side; three angles alone cannot fix the size. Plane (flat) triangles only, angles in degrees. The drawing is to scale but not a measured diagram. Nothing you enter leaves your device.
