Here you learn the basic geometric terms (planimetrics): the types of triangles and polygons the parts of a circle and the important lines and segments such as a median of a triangle and a tangent to a circle.

There are three levels: 1) the first one about elements of triangles; 2) the second about types of polygons; 3) the last level is about the circle and its parts.

The app is translated into 9 languages including English Spanish and many others. So you can learn the names of the geometric figures in any of them.
