There are cathedrals all over Europe, in Spain, in England, in France, in Germany, and in Italy. The architecture of cathedrals is based on the old Roman basilica.

Distance Formula and Pythagorean Theorem. The distance formula is derived from the Pythagorean theorem. 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. The distance formula is. $ \text{ Distance } = \sqrt{(x_2 -x_1)^2 + (y_2- y_1)^2} $. Below is a diagram of the distance formula applied to a picture of a line segment.
