Question

there are two blue l - shaped figures and four options: translation, reflection, rotation, none of these.

Explanation:

Step1: Analyze Translation

Translation moves a figure without rotating or reflecting it. The two figures don't have the same orientation as a simple translation would preserve orientation, so translation is not correct.

Step2: Analyze Reflection

Reflection flips a figure over a line. The two figures appear to be rotated, not reflected.

Step3: Analyze Rotation

Rotation turns a figure around a point. The top figure can be rotated (90 - degree rotation, for example) to match the bottom figure's orientation.

Step4: Analyze "None of these"

Since rotation applies, this is incorrect.

Answer:

C. Rotation
