75 points to whoever does all of this for me. 1. Draw, in black, the triangle with vertices (-3, 2), (1, 1), and (2, 5).2. Draw the triangle's image under the dilation (x, y ) → (2x, 2y).3. Explain clearly why the two triangles must be similar.4. How could a dilation create a figure which is congruent to the original one? [Hint: there are two ways.](share imgur link)
