  1. Distance Formula Geometry on the Coordinate Plane

  2. 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

  3. Distance Formula & Perimeter Find the perimeter of the polygon formed by connecting the coordinates A(-1,0), B(0,-4), C(8,-2), D(7,2). A(-1,0) A(-1,0) A(-1,0) B(0,-4) B(0,-4) B(0,-4) B(0,-4) C(8,-2) C(8,-2) D(7,2) D(7,2) A(-1,0)
