Question

Which shows a proper reflection across the red dashed line?

Answer 1

B

Explanation:

A reflection is basically what you would see if you were to flip an image. Try taking a photo, and flipping it! A is incorrect because it is only a translation* rather than a reflection.

Translation*: Translation is when a shape moves on the graph, but does not change size, dimensions, or angle.

Answer 2

B

Explanation:

A proper reflection is like seeing the same shape or flip shape.

A is incorrect because the triangle supposes to face each other. B look correct because it looks the same on both sides. So, the answer is B.
