How do you find the dilation of a triangle?

Draw the dilation image of the triangle with a center at the origin and a scale factor of two.

Dilatation is the transformation that produces and image that is the same shape as the original, but different size. So, in order to find the dilatation of a triangle, you need to multiplícate by a scale factor the given coordinates. An ex: A'(0,2), B'(2,-1), and C'(-2,-2) , lets say that you are going to múltiple by 2, the formula would be (2x, 2y), and the results will be A'(0,4) B'(4,-2), C' (-4,-4).
