Explain how each figure was moved. Write translation, reflection or rotation.

Here is how each figure was moved:

a) The figure has moved to a new position without changing its orientation. The triangle inside is still pointing upwards. This is a translation.

b) The figure has been flipped horizontally. The triangle inside, which was pointing right, is now pointing left, creating a mirror image. This is a reflection.

c) The figure has been turned around a point. The triangle inside, which was pointing right, is now pointing downwards. This change in orientation indicates a turn. This is a rotation.

a) $\boxed{\text{Translation}}$

b) $\boxed{\text{Reflection}}$

c) $\boxed{\text{Rotation}}$
