look at this shape:\nwhich image shows a rotation?\na\nb\nc

Explanation:

Step1: Recall rotation definition

Rotation is a transformation that turns a figure around a fixed point. The shape should have a different orientation (like turned 90°, 180°, etc.) but same size and shape.

Step2: Analyze each option

• Option A: The shape's orientation is not a rotation (looks like a reflection or different transformation).
• Option B: This is a translation (moved down, same orientation as original).
• Option C: The shape is rotated 180° (or 90°? Wait, original L-shape: if we rotate 180° or 90°, the third image (C) has the L-shape flipped in a way that's a rotation. Wait, original: top part is left, then extends right. In C, it's like rotated 180°? Wait, no, let's see: original has the "corner" at top-left of the blue shape. In C, the corner is at top-right, but the shape is rotated. Wait, actually, rotation changes the orientation. Let's check: original is L-shape with the vertical part on the left, horizontal on the bottom. In C, vertical part is on the right, horizontal on the top. So that's a rotation (180° or 90°). Option B is same orientation, just moved down (translation). Option A is a different shape (like a mirror, reflection). So C is the rotation.

Answer:

C
