Use the Polygon tool to draw an image of the given polygon under a dilation with a scale factor of 14 and center of dilation (0, 0)(0, 0) .
cordinates are (12,12),(12,4),(8,0),(5,8)
The equation for finding a new point is
[ Old Point - Dilation Center ] * Scale Factor + Dilation Center
However....since the origin is the Dilation Center, this simplifies to
[Old Point] * Scale Factor....so we have
(12,12) * 14 = (168,168)
(12,4) * 14 = (168, 56)
(8,0)*14 = (112, 0)
(5,8) *14 = (70, 112)
