Question

look at this shape: image of a green triangle on a grid which image shows a rotation? images of three green triangles labeled a, b, c on grids; options a, b, c below

Explanation:

Step1: Recall rotation definition

Rotation is a transformation that turns a figure around a fixed point, changing its orientation.

Step2: Analyze each option

• Option A: The triangle's orientation (shape and angle) is different, looks like a reflection or different triangle, not rotation.
• Option B: The triangle's orientation (the direction of the vertices) has changed, consistent with a rotation (e.g., rotated around a point, changing the angle of the sides relative to the grid).
• Option C: The triangle looks like a translation (moved without changing orientation), not rotation.

Answer:

B
