Distance Formula Geometry on the Coordinate Plane
Recall: the distance formula is used to find the distance between two points on a graph. • Find the length of the legs of the right triangle: vertical leg : |y2 – y1| horizontal leg: |x2 – x1| Demonstration and Explanation: Find the distance on the coordinate plane between the coordinates A(2,-3) and B(4,1). • Using the Pythagorean Theorem: c2 = a2 + b2 • Graph the coordinates • Draw the line segment connecting the two points (we need to find the length of this line segment.) • Create a right triangle by drawing a vertical line through one end point and a horizontal line through the other end point. units
