## Geometry Solver

SamF

1

The app will help you solve tasks from the geometry.

With the app, different forms such as solving (Triangular, trapezoidal, square, circle, ...)

This requires the app any known values are given,e.g. the side lengths of a triangle. The app will now calculate the remnant values such as area and perimeter as well as the angles of the triangle.

Of course, other combinations of the default values are possible, such as 2 angles and a side ...

The app is bilingual in English and German.

## Measure Threads with 3 wires

Sometimes it is not possible to use a thread measuring micrometer to measure screw threads, so the measure over three wire method must be used.

Use this application to quickly and easily do all the calculations required to measure ISO metric and UN 60 degree threads, Acme and Stub Acme threads, and Trapezoid threads with wires. The only thing it can't do is help you to hold the three wires in place AND use the micrometer at the same time!

You start with the nominal thread size, thread pitch (or TPI) and wire size.

You cancalculate pitch diameter or measurement over wires or both.

The thread measurement over wires calculator will also give you the best wire size.
