To identify the degree of rotation for Rectangle A B C D to coincide with Rectangle A' B' C' D', centered about the point (1, 0), we need to look at their relative positions and orientations in the coordinate plane.
-
Quadrant Location: Rectangle A B C D is in quadrant 2, while Rectangle A' B' C' D' is in quadrant 1. This indicates that they are opposite each other across the y-axis.
-
Standard Positions:
- In quadrant 2, the rectangle's vertices would typically have x-coordinates that are negative and positive y-coordinates.
- In quadrant 1, the rectangle's vertices would have positive x and y coordinates.
-
Rotation Analysis:
- To rotate from quadrant 2 (where the rectangle is angled in a specific orientation) to quadrant 1, we would need to rotate the figure.
- The transformation indicates a clockwise rotation since we are moving from quadrant 2 to quadrant 1.
-
Degree of Rotation:
- The rotation from the positive y-axis towards the positive x-axis can be measured as a 90-degree rotation.
- Since it is moving clockwise, this would be noted as -90 degrees for clockwise rotation.
Therefore, the rectangle is rotated 90° counterclockwise or -90° clockwise.
Please provide any specific degrees if necessary, but typically it would be denoted as 90° counterclockwise or -90° clockwise.
