For each exercise:

- Try to
__predict__what will happen,**before**using the software. First write down your own prediction, then describe it to the rest of the group. __Test__your predictions by playing with the program. Discuss the results, and write down a__revised__group answer, based on what you learned.- Finally,
__explain__the revised predictions.

A.Create three points in the plane, forming antriangle.equilateral

- Where is the mean?
- Where is the mediancentre?
