Triangles

The Triangles Chrome extension allows you to effortlessly calculate the missing lengths and angles of any triangle. By entering just three known parameters, including at least one side length, it automatically computes the unknown sides and angles. The tool leverages fundamental trigonometric principles such as the law of sines, law of cosines, and the angle sum property to deliver accurate numerical and graphical results.

With clear visual cues—white for valid inputs, yellow for missing values, and red for impossible solutions—Triangles helps users quickly determine the feasibility of their inputs. Additionally, in ambiguous cases where two solutions exist, the extension conveniently presents both possibilities. This makes it an essential tool for students, educators, engineers, and anyone needing quick and precise triangle calculations right in their browser.
