Risolve la geometria

Run the full performance of simple geometry problems

It performs, immediately and for free, the solution of a geometry problem for middle and elementary school. There are all the formulas used and all the intermediate steps and intermediate calculations. The geometric figures are the fundamental ones; plane shapes: triangle, square, rectangle, parallelogram, deltoid, trapezoid, rhombus, circle, pentagon, hexagon, ... up to the dodecagon; solid figures: cube, parallelepiped, pyramid, sphere, prism, cone, cylinder, solids of rotation.

Just write the trace of the problem in Italian, even with a simple copy and paste.

The solution is carried out automatically, with all the necessary formulas and steps. The geometric figure is drawn automatically and to scale, according to the dimensions given by the problem.

If the solution is not found, a screen is still available in which to enter the known measurements of a geometric figure and choose between: perimeter, area, diagonals, etc.

It's not perfect, that is, it doesn't solve many problems; or fails to read the trace of the problem, giving incorrect results.

Internet connection is required.

The application is free.

Solves more than 23,000 different problems for free.

This application is a small free part of the Electric School website's paid geometry calculator, which contains more than 500,000 solved problems.

Speaking of reviews.

Who, in the reviews, says that it is paid, is telling one of the many lies that he usually tells.

The application is free.

The application solves more than 23,000 problems for free. It takes at least three hours for an application developer to post a problem. So it's bad to tell someone who has worked 9,000 hours for free, to say that the application is paid for.

Anyone who says in the review that it does not solve the problems means that they have not tried it well.

Before expressing an evaluation, it is necessary to insert at least three different problems, i.e. on different geometric figures. By inserting at least one easy problem, i.e. one of the first problems of each figure reported in the textbook.

It is also necessary to make a distinction between the "e" and the "is"; between the "a" and the "ha".

Punctuation is important, i.e. dot ".", comma "," or semicolon ";" or the space " " between two words, when required by the track.

If the problem has been written well, without errors and with units of measurement, as in the textbook, it will be solved if it belongs to the first problems reported in the textbook, for each figure.

Problems with a single plane figure are solved almost all.

Problems with multiple plane figures, on the other hand, or with multiple solids are not all solved.

As of June 2017, I have added an automatic module that alone solves more than 20,000 plane geometry problems. In practice it combines the 8 regular polygons (pentagon, hexagon, heptagon, up to the dodecagon) with one of the 7 fundamental polygons (triangle, square, rectangle, rhombus, trapezium, parallelogram, circle). This module alone solves 2 x 8 x 1236 = 19,776 problems; where 1.236 are the problems that can be solved with a single polygon.

The application takes into account the problems most requested by users, that is, it solves the most requested problems.

Less requested problems are solved comprehensively only in the paid version, which contains more than 470,000 more solved problems than this free application.

If there are problems in the installation or in case of crashes, it is preferable to use the recent application:

which is called a geometry calculator.
