Geometric Handshake

The geometry students conduct the handshake experiment to explore mathematical modeling. They determined that the number of handshakes within a group of people is found by the formula n(n-1)/2 where 'n' is the number of people participating. This then leads to determining how many lines can be connected between 'n' number of points on a plane. Acting out situations is a great way to problem-solve.
