Question

Which translation rule can be used to prove that triangle R(10,6), S(8,4), T(6,6) and triangle R'(7,4), S'(5,2) T'(3,4)are congruent?

Answer 1

After the translation point R went 3 units left and 2 units down. Similarly all the other points went 3 units left and 2 units down.

So the translation rule is (x-3,y-2)

Hope this helps :)
