The description of Trisolve
100% Free (*scroll to details below)
The best triangle calculator.
Great for geometry students, teachers, carpenters, navigators, orienteers, surveyors, astronomers,... or anyone wanting to solve triangles.
The only triangle calculator that draws the values you enter and enters the values you draw.
Enter what you know, whatever you know, and the app dynamically tells you everything that can be calculated, including inverse calcuations. If any value is possible to solve, Trisolve solves it. If it is impossible to solve, Trisolve lets you know that too.
No need to press an enter key to solve your triangle. Just draw or enter and immediately visualize the solution.
Easily clear and restore individual values by touching the value's icon.
Trisolve calculates triangles using sides and angles, xy, or rΘ coordinate systems, including combination of each to suit your situation.
Solves sides, angles, heights, perimeter, area, vertex positions and multiple centers. Trisolve also allows you to enter heights, perimeter, area, vertex positions and centers, not just sides and angles like other triangle solvers.
Categorize scalene, isosceles and equilateral as well as acute, right, and obtuse triangles. Identifies and solves ambiguous triangles.
Angle measures for degrees, radians, grads, deg min sec, % grades, and much much more. Unit conversions are easy, just choose the units and Trisolve converts automatically without reentry.
Transformations include translate, rotate, reflect and dilate. Transformations are based on the coordinate system to facilitate easy understanding by students while giving maximum flexiblity for advanced users.
Results are calculated using numerically stable trigonometric algorithms giving the most precise results possible even in extreme engineering applications. Unlike many triangle solvers that give wrong answers under extreme conditions, Trisolve handles these cases with precision.
All values can be both user entered or calculated in any combination. For example, enter the triangle base and height and area is calculated. Enter area and height and the triangle base is calculated. Enter any value in any order and the correct formula is applied. No other app calculates geometric inverse functions like Trisolve does.
Calculable values are shown with easily identifiable color icons while user entered values are indicated by high contrast monochrome icons suitable for color blind users.
Inputs can be cleared and restored individually by clicking the associated value's icon for experimental adjustments.
Field sizes are dynamically adjusted based on the user's entered information so extreme precision values fit on the smallest phone screens.
Trisolve is the best triangle solver on Google Play, free or paid, period.
