Question

which type of transformation takes triangle a to triangle b?

Explanation:

A reflection flips a figure over a line of reflection. Here, triangle A is flipped over the vertical line \(n\) to get triangle B. In a translation, the figure would just slide without flipping, and in a rotation, the figure would turn around a point. Since triangle A is flipped over a line to form triangle B, it's a reflection.

Answer:

Reflection
