Question

look at this shape:
image of a yellow quadrilateral on a grid
which image shows a rotation?
images labeled a, b, c of yellow quadrilaterals on grids
options: a, b, c

Explanation:

Step1: Recall Rotation Definition

Rotation is a transformation that turns a figure around a fixed point (center of rotation) by a certain angle, preserving shape and size, and changing orientation.

Step2: Analyze Option A

Option A's shape appears to be a reflection or translation (orientation similar but not rotated). The triangle's "slanted" side direction doesn't match a rotation of the original.

Step3: Analyze Option B

Option B's shape: The original has a right angle with a slanted side going down-right. Option B's triangle has the slanted side direction changed (rotated, e.g., 180° or 90° rotation), matching the rotation's orientation change while preserving shape/size.

Step4: Analyze Option C

Option C's shape looks like a translation (same orientation, just moved), not a rotation (orientation unchanged or not matching rotation).

Answer:

B. Option B
