Math Problem Statement
Solution
The problem in the image asks for the coordinates of the point after a 90° clockwise rotation about the center point .
Steps to solve:
-
Translation to the origin: First, subtract the center coordinates from the point to translate the point to a coordinate system centered at . This will give us the relative coordinates of the point: So, the translated point is .
-
Rotation by 90° clockwise: The formula for a 90° clockwise rotation of a point around the origin is: Applying this to the translated point : So after rotation, the point is in the translated system.
-
Translation back to the original coordinates: Now, we translate the point back to the original coordinate system by adding the center point :
Thus, after rotating the point 90° clockwise around , the new coordinates are .
