Trisolve: Triangle Calculator 1.1.9

Great for students, teachers, carpenters, orienteers, orienteers, surveyors, astronomers... or anyone who uses triangular geometry. Enter what you know, whatever you know, and the app will automatically tell you everything that can be calculated from even one piece of information. If there is a value that can be solved, Trisolve will solve it immediately.

Trisolve solves triangles using sides and angles, xy or rΘ coordinate systems, or any combination of each that suits your situation.

Calculate sides, angles, heights, perimeters, areas, vertex positions and multiple centers. Trisolve also allows you to enter sides, angles, heights, perimeters, areas, vertex positions and multiple centroids, not just sides and angles like other triangle solving software.

Classify trapezoidal, isosceles, and equilateral shapes as well as acute, square, and obtuse triangles. Identify and resolve ambiguous triangles.

Protractors for degrees, radians, grads, degrees minutes seconds, % points and more. Converting units is easy, just select the unit and Trisolve will automatically convert without re-entering.

Transformations include translation, rotation, reflection, and dilation. Transformations are adjusted based on the coordinate system to help students understand while providing maximum flexibility for advanced users.

Calculate results using a numerically stable trigonometric algorithm, providing the most accurate results possible even in harsh engineering applications. Unlike many triangle solvers that give wrong answers under extreme conditions, Trisolve handles these cases correctly.

All values ​​can be entered by the user or calculated in any combination. For example, enter the base of a triangle and calculate the height and area. Enter the area and height and calculate the base of the triangle. Enter any value in any order and the correct formula will be applied forward and backward, no matter what you enter. No other application has this feature.

Calculated values ​​are displayed with easily recognizable color icons while user-entered values ​​are represented with high-contrast monochrome icons suitable for blind users color.

Inputs can be cleared and restored individually by clicking on the associated value's icon for experimental adjustments.

Field size is dynamically adjusted based on user input so that extremely accurate values ​​fit even the smallest phone screens.
