ΔPQR has vertices at P(2, 4), Q(3, 8) and R(5, 4). A similarity transformation maps ΔPQR to ΔABC, whose vertices are A(2, 4), B(5.5, 18), and C(12.5, 4). What is the scale factor of the dilation in the similarity transformation? A) 2 B) 2.5 C) 4 D) 3.5

    one approach is to do a sketch to "see" better the corresponding sides will be in the same ratio example find length PQ/length AB = QR/BC

    start by trying at least read the response plot the points find the lengths scale factor is the ratio of the original to the new

    I'm gonna go on a limb here and say is it B? Because that seems to be the only one that makes sense to me.

    I don't know I have to do the problem. May take a little longer than guessing but much greater change of being correct

    I am just overall confused on this stuff, so any help you can provide is fantastic.

    @TillLindemann All your posts make the excuse of 'being confused' The best way of NOT being confused is to learn from what you are being told and MORE importantly TRY what you are being told - if you get it wrong, at least you will learn If you wait for the answer (even if it is someone explaining every step with you not contributing) then you will be confused about this stuff for ever

    May take a little longer than guessing but much greater change of being correct (I like!)

    I am confused simply because I do not understand anything regarding Geometry. Sure I try and understand what you people are saying to me, but it generally does not make sense.

    Make a sketch plot of the 2 triangles |dw:1434987981616:dw| like this - with the correct positions from the question

    Do your own plot , using the numbers from the question - put the numbers on the corners
