Math Problem Statement
Solution
The image you uploaded presents a task involving a rotation and asks to determine the coordinates of point , given the preimage and a rotation of 180°.
To solve this:
Rotation of 180°
When a point is rotated 180° about the origin, the coordinates of the point change as follows: So, applying this rule to point :
Thus, the coordinates of after a 180° rotation are .
The correct answer is A'(2, 5).
Would you like more details or have any other questions? Here are five related questions that expand on this concept:
- How do the coordinates change under a 90° clockwise rotation?
- How do you perform a reflection over the x-axis for any point ?
- How do the coordinates change under a 270° counterclockwise rotation?
- What is the formula for a 180° rotation about a point other than the origin?
- How would the rotation change if it was about a point different from the origin?
Tip: Always check the direction and center of rotation when solving transformation problems.
