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. Play this game to review Geometry. The formula looks like this.
Find the midpoint of.
You can plug in the two endpoint x- and y- values of a diagonal line and determine its length. The distance formula is derived from the Pythagorean theorem. Find the midpoint of. Similarly for vertical lines b 0 the distance between the same point and the line is ax 0 c a as measured along a horizontal line segment.
