Since the origin is the center of dilation. Take every vertex in the polygon ABCD and multiply it by 2 since the dilation factor is 2. It will result to polygon A'B'C'D'. Compare then the points given to the new points after dilation.
Are we talking about edges or the physical sides of the triangle?
If edges (corners / angles of the triangle), then no, because it doesn’t add up to 180. I don’t think the measurements of the sides matter, tho.
