look at this shape:
image of a green triangle on a grid
which image shows a rotation?
three images labeled a, b, c, each with a green triangle on a grid
options: a, b, c
submit

Explanation:

Step1: Recall rotation definition

A rotation is a transformation that turns a figure around a fixed point, changing its orientation. A translation moves the figure without rotating or reflecting, and a reflection flips it over a line.

Step2: Analyze each option

• Option A: The triangle seems to be a translation (moved without changing orientation/rotation) or maybe a reflection, but not a rotation. Its orientation relative to the original doesn't show a turn.
• Option B: The triangle has a different orientation, indicating it has been rotated (turned) around a point. The angle and direction of the triangle suggest a rotation.
• Option C: The triangle looks like a translation (moved vertically or horizontally without rotation), as its orientation is the same as the original.

Answer:

B. Option B
