The figure shows Triangle ABC and some of its transformed images on a coordinate grid:


Which of the four triangles was formed by a translation of Triangle ABC?

1
2
3
4

Answer 1

Answer: Triangle 4

The specific translation or shifting is "move 9 units to the right and 4 units down".

We can prove this by looking at something like point A(-10,2) and note how it moves to (-4,-2). Going from (-10,2) to (-4,-2) is exactly 9 right and 4 down.

In terms of x,y notation the translation rule is
`(x,y) \to (x+9,y-4)`
