Question

A figure consists of a triangle attached to a square such that the triangle points up. If the figure is rotated \(90^\circ\) clockwise, then where will the triangle point?

• A. Left
• B. Right
• C. Downward
• D. Upward

Hint:

Think of a clock face: moving \(90^\circ\) clockwise from 12 o'clock reaches 3 o'clock, which corresponds to the right direction.

Answer 1

The Correct Option is B

Concept: A clockwise rotation turns an object in the same direction as the hands of a clock. \[ \text{Up} \rightarrow \text{Right} \rightarrow \text{Down} \rightarrow \text{Left} \] for every successive \(90^\circ\) clockwise rotation.

Step 1: Identify the initial direction. The triangle initially points upward. \[ \text{Direction}=\text{Up} \]

Step 2: Apply the rotation. A \(90^\circ\) clockwise rotation moves the direction one quarter-turn clockwise. \[ \text{Up} \xrightarrow{90^\circ \text{ clockwise}} \text{Right} \]

Step 3: Conclusion. After rotation, the triangle points to the right. \[ \boxed{\text{Right}} \] Hence, the correct answer is Option (B).
