- Form right triangles by connecting the origin, a point on the x-axis, and a point on the y-axis (or a point with another point vertical and another point horizontal).

**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.
