Question

look at this shape:
image of a blue trapezoid - like shape on a grid
which image shows a rotation?
images labeled a, b, c of blue shapes on grids
options: a, b, c

Explanation:

Step1: Recall Rotation Definition

Rotation is a transformation that turns a figure around a fixed point. The shape's orientation (angle, direction) changes, but size and shape remain.

Step2: Analyze Each Option

• Option A: The triangle's orientation (angle of the hypotenuse, position of the right angle) is rotated compared to the original. The right angle's position and the slant side's direction match a rotation (e.g., 90° or 180° rotation could adjust it to this).
• Option B: This looks more like a reflection or translation with a flip, not a rotation (the slant side's direction is mirrored, not rotated).
• Option C: This is the original shape (translation or no change), not a rotation.

Answer:

A. Option A (the first image labeled A)
