Click the **Terms** tab above for a more detailed description of each entry.

#### IMPORTANT!

Please double-check my calculations before considering them to be valid, as I can't test for all possible entries. If you do discover an issue with the calculations, please use the feedback form below the calculator to let me know the settings and entries that generated the issue so I can troubleshoot the problem. Thank you!

Tap the "Solve" button, which will solve for the missing sides and/or angles, show the steps taken to solve the triangle, and, if you have an HTML5 compatible web browser, draw the triangle.
