    Pamela will draw a quadrilateral IJKL similar to quadrilateral EFGH. The length of IJ should be 6 and I should be located at point (1, -3). At which points will vertices J and K be located?

    right ijkl is similar to efgh this means ij is proportional to ef if ij is 6 and ef is 3, then what is the proportion

    ok this means the sides of ijkl are 2 times larger than the sides of efgh you know where point I is so start by drawing that you also know where point J is which is 6 units away from I, so you can draw that look at efgh for information and keep plotting ijkl until you get a similar quadrilateral then make note of where point k and point l are

    @completeidiot I got (3, 1) for J, and (5, -5) for K

    G is 4 units to the right from F that means j is how many units away from k?

    dont know where the post went but yes it is 8 units to the right, so you can draw K

    now draw it on your graph and then you'll have a similar quadrilateral
