The lines AA', BB' and CC' are congruent lines.
To perform the translation, we make use of the following coordinates:
A = (1,2)
B = (5,-4)
C = (7, 8)
When translated by (x+4, y-3), we have
(x,y) ⇒ (x+4, y-3)
This gives
A' = (5,-1)
B = (9,-7)
C = (11, 5)
Next, we draw the triangle ABC, the image A'B'C' and the two lines; one from A to A' and the other from B to B'
From the graph (see attachment), we can see that the lines AA' and BB' are congruent lines.
This would be the same when the line is drawn from points C to C'
This is so because the same transformation is applied to the vertices of the triangle ABC
