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} $.
Confidence votes 7.2K. We assign coordinates to point on the plane and use those coordinates to tell us about the points. For example, the distance formula tells us how far apart they are, the midpoint formula tells us where there midpoint is.n a coordinate plane, you have a graph. the graph is spilt into 4 intervals. for example if you get a number like (4,3) then you move to the right four and go up 3. if its a â¦ negative number like (-4,-3) then you move to the left four and go down three.
