A quadrilateral EFGH is drawn on a coordinate grid as shown below.

2. LoveToDance22

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?

3. completeidiot

do you know what similar means?

4. LoveToDance22

proportional sides and congruent angles?

5. completeidiot

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

6. LoveToDance22

@completeidiot 6/3 so 3/1 ?

7. completeidiot

do you want to correct your mistake?

8. LoveToDance22

oh lol sorry 2/1

9. completeidiot

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

10. LoveToDance22

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

11. completeidiot

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

12. completeidiot

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

13. LoveToDance22

oh sorry haha I though it was wrong so I deleted it

14. completeidiot

now do the same thing to find L

15. LoveToDance22

is it 10?

16. completeidiot

yes

17. completeidiot

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

thanks! :)
