Question

Which best explains whether or not triangles RST and ACB are congruent? The figures are congruent. ΔRST can be mapped to ΔACB by a reflection over the x-axis and a translation 2 units to the left. The figures are congruent. ΔRST can be mapped to ΔACB by a reflection over the y-axis and a translation 2 units down. The figures are not congruent. Point R corresponds to point A, but S corresponds to B and T corresponds to C. The figures are not congruent. Point R does not correspond with point A.

Answer 1

The answer is A, just took the test.

A was the only obvious choice because a reflection across the x-axis will get triangle ACB to triangle RST. I second guessed this answer because sliding triangle ACB two units to the left would not map these two triangle directly on top of each other, but it will if u translate triangle ACB two units to the left before reflecting across the x-axis.

Answer 2

Answer:

A) The figures are congruent. ΔRST can be mapped to ΔACB by a reflection over the x-axis and a translation 2 units to the left.
