Finding the Shortest Distance Between Two Points

This activity is designed to teach students who are blind or visually impaired to find the shortest distance between two points.

Note: In order to make this lesson more kinesthetic, the teacher makes a right triangle on the floor using masking tape.  There are two parts of the exercise; 1: to have the student prove that the shortest distance between two points is a straight line and 2: to have the student prove that by using the Pythagorean Theorem they will accurately calculate the shortest distance.
