This right triangle calculator is a handy tool designed to help users calculate the missing sides and angles of a right triangle based on the information they provide. By selecting one of three options—Perpendicular and Hypotenuse, Perpendicular and Base, or Base and Hypotenuse—users can input two known values, and the calculator will instantly compute the third side. Whether you’re a student studying trigonometry or someone who needs quick calculations for work, this tool makes finding the missing dimensions of a triangle simple and accurate.

In addition to the side lengths, the calculator also provides the angles of the triangle (θ1 and θ2), calculated using inverse trigonometric functions. The results include the triangle’s dimensions and the trigonometric ratios—sine, cosine, and tangent—for both angles. This feature is handy for those studying trigonometry, as it allows them to quickly check their work or deepen their understanding of how these ratios relate to the geometry of the triangle. With an intuitive interface and instant results, this calculator is a valuable resource for anyone working with right-angled triangles.
