So, what you are going to need to do first, is plot head of the original lettered points, and label them! The coordinates were provided, so that should be easy!! After that, you need to <em>dilate</em>, which means to change the size, not necessarily make smaller. Dilations use multiplication, so you would multiply, so you'd multiply to the point values by two.
i seriously hope this makes sense, but im here if you need more help!!
for this problem you would have to find the coordients on the graph and then once you find all the coordients you would attach the lines together which should be a triangle.
