Which option rotates the square 90 degrees (one quarter turn) clockwise?
The Correct Answer and Explanation is:
The correct answer is the first option on the left (which is already selected).
Explanation:
To solve this problem, we need to understand what happens to a shape when it is rotated 90 degrees clockwise.
In the original image, the black circle is located in the top right corner of the square. When we rotate the square 90 degrees clockwise, every point on the square moves one quarter turn to the right:
- The top right corner becomes the bottom right corner.
- The bottom right becomes the bottom left.
- The bottom left becomes the top left.
- The top left becomes the top right.
So, the black circle that was originally in the top right will move to the bottom right.
Let’s now examine the four options:
- First option (leftmost) – The black circle is in the bottom right corner. ✅ This is exactly where it should be after a 90-degree clockwise rotation.
- Second option – The black circle is in the top left corner, which would correspond to a 90-degree counterclockwise rotation, so ❌.
- Third option – The black circle is still in the top right, which means there’s no rotation at all, so ❌.
- Fourth option – The black circle is in the bottom left, which would result from a 180-degree rotation, so ❌.
Summary:
When rotating a shape 90 degrees clockwise, all positions move one corner over in the direction of a clock’s movement. Thus, the top right corner becomes the bottom right. Therefore, the first option correctly shows the rotated shape.
