Question

If triangle ABC is translated 4 units to the left and 2 units downward, are the pre-image and image congruent? Why, or why not?

Yes, distance is preserved and angle measure is not
No, angle measure is preserved but distance is not
Yes, distance and angle measure are preserved
No, neither distance nor angle measure are preserved

Answer 1

If the triangle is only being moved horizontally and vertically, are any of the sides or angles changed?

Answer 2

Good, so the pre image and image are congruent due to their distances and angle measures both being preserved
