Question

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

Explanation:

Step1: Recall Rotation Definition

Rotation is a transformation that turns a figure around a fixed point, changing its orientation. The original triangle has a right angle with the vertical side on the right.

Step2: Analyze Option A

Option A's triangle has the right angle at the bottom, and the hypotenuse is horizontal, showing a 90 - degree rotation (or similar) from the original, changing orientation.

Step3: Analyze Option B

Option B's triangle is a reflection or translation - like, as the vertical side is on the left but the orientation of the triangle's parts (relative to the grid) doesn't match a rotation from the original.

Step4: Analyze Option C

Option C's triangle looks like a translation (slid) as the orientation and position relative to the grid lines are too similar to the original, no rotation - induced orientation change.

Answer:

A. Option A
