Question

for each pair of figures below, choose how they are related.

Explanation:

• First pair: The figure is turned around a point, which is the definition of rotation.
• Second pair: The figures are of different sizes. Translation, reflection, and rotation preserve size. So it is none of these.
• Third pair: The figure seems to be flipped over a line (a mirror - like image), which is reflection.
• Fourth pair: The figure is moved without rotation or reflection (all corresponding points move the same distance in the same direction), which is translation.

Answer:

1. Rotation
2. None of these
3. Reflection
4. Translation
