The distance formula is derived from Pythagorean theorem. The triangles will help you remember these three rules. A2 b2 c2 a2 b2 c2 where.
Heres how we get from the one to the other.
X 2 x 1 2 y 2 y 1 2. To find the distance between two points x 1 y 1 and x 2 y 2 all that you need to do is use the coordinates of these ordered pairs and apply the formula pictured below. Besides this can be understood in a better sense by seeing it in formula form. Call one point Point 1 x1y1 and make the.
