Skeletal surveys are also used with suspected non-accidental injury in children (CE guidelines state that 19 images of the child are taken.) These are reported on by a consultant paediatric radiologist and often copies are made.
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} $.
The length of the hypotenuse is the distance between the two points. Since this format always works, it can be turned into a formula: Distance Formula: Given the two points (x1, y1) and (x2, y2) , the distance between these points is given by the formula: Don't let the subscripts scare you. They only indicate that there is a first point and a second point; that is, that you have two points. Whichever one you call first or second is up to you.
