Re: Use similar right triangles

If the coordinates of the points and the ratio are given, it could be solved with similar right triangles.
Consider the points (0,15) and (20,0) and a ratio of 2:3.
The legs can be determined from the coordinates. The sum of the ratio can be used for the hypotenuse; there is no need to calculate the distance.
The proportions would be 2/x=5/20 and 3/y=5/15, (8,9).
I would also accept 3/x=5/20 and 2/y=5/15 for (12,6) for the righttoleft thinkers.
