Question

Which transformation was applied to ABC to transform it to DEF?

Answer 1

So the Answer will be D.

Explanation:

Cuz if you look it up online it will give you words or maybe links that youu shouldn't look at cuz they don't really give it to you. It shows that ''A rotation turns each point on the preimage a given angle measure around a fixed point or axis. Each point on triangle ABC is rotated 45° counterclockwise around point R, the center of rotation, to form triangle DEF.'' So indee that D. is right. (I am only 11 and i am helping lol)

Answer 2

The transformation that was applied to △ABC to transform it to △DEF is reflection over the x -axis.

The triangles have the same shape and size, but they are flipped upside down. This is the defining characteristic of a reflection over the x -axis.

A reflection over the y -axis would have flipped the triangle left to right, not upside down.

A translation would have moved the triangle to a different location on the coordinate plane, but it would not have changed its shape or orientation.

A rotation about the origin would have rotated the triangle around a fixed point, but it would not have flipped it upside down.

Therefore, the only option that makes sense is A. Reflection over the x-axis.
