Question

look at this shape: image of a purple l - shaped figure on a grid which image shows a rotation? images of three figures labeled a, b, c below, each on a grid

Explanation:

To determine which image shows a rotation, we analyze the original shape (an L - shaped figure) and the properties of rotation. A rotation of a figure means that the figure is turned around a fixed point, and its orientation changes while the shape and size remain the same.

• Option A: The figure in option A looks very similar to the original figure in terms of orientation. It seems more like a translation (a slide) rather than a rotation, as the direction of the L - shape has not changed significantly.
• Option B: The figure in option B has a different orientation compared to the original. If we imagine rotating the original L - shaped figure, this orientation is consistent with a rotation (for example, a 90 - degree or 180 - degree rotation depending on the direction). The "arm" of the L that was originally pointing in one direction is now pointing in a new direction that is consistent with a rotational transformation.
• Option C: The figure in option C does not match the expected orientation of a rotated version of the original L - shape. Its overall form and the direction of the L - shape's arms do not align with what we would expect from a rotation of the original figure.

Answer:

B
