Use the Pythagorean Theorem to find the missing lengths of the sides of a right triangle.  triangle that has an opposite side of length 3 and a hypotenuse of length 4.  Determining all of the side lengthsand angle measures of a right triangle is  Let's look at how to do this when you're given one side lengthand one acute

A’b’c’ are the coordinates to the new location of the transformed triangle abc. find the distance between the coordinates points to use for your calculations.
