Draw the image of ABC under a dilation whose center is P and scale factor is 1/3

From the figure and statement provided, select the proper to prove statement. through a point outside a line one line can be drawn parallel to the line. mn= ab ab + bc= ac mis parallel to ! ab=bc als parallel to b

I'll give brainliest if you answer right : )
