Question

triangle fdp is reduced with a scale factor of 1/2 and a center of (0,0). Find the coordinates of the new vertices.

Answer 1

The new points are:
P' (-3, 0)
F' (1, 2)
D' (0, -2.5)

The shape is being transformed with a dilation of a scale factor of 1/2. This means that we take the given points and multiply them by 1/2 to find the new points. 

Look on the graph for the current points and multiply each one by 1/2. You will have the new points.
