Learning Geometry By Simulation

To solve a problem our mind uses intuition and experience. 
The intuition is more influential than experience and it is responsible of many choices we make.
Thinking fast is a characteristic of our intuition, thinking slowly is an attribute of our knowledge. 
As an example, suppose we have 4 triangle and we have to decide
if the triangles are congruent. First idea   that comes in our mind is to compare visual triangles
to decide if they coincide. Second idea is to decide by measuring if they are congruent. 
To support first solution we need some tools to simulate moving of triangles, without deformation as is shown. 
In this course we demonstrate how visual simulation aims our intuition for solving geometrical problems.
