Math Problem Statement
What is the answer
Solution
In this problem, you're asked to rotate the figure 90° clockwise and then analyze the two statements:
Step-by-Step Solution:
-
Identifying Initial Coordinates:
- Point is at (-7, 0).
- Point is at (0, 0).
- Point is at (0, -4).
-
Applying a 90° Clockwise Rotation:
- When rotating a point 90° clockwise around the origin, the new coordinates become .
Let's apply this transformation to each point:
- Point becomes .
- Point stays .
- Point becomes .
-
New Figure: After rotating the figure, the new positions of form a rotated shape on the graph.
Evaluating the Statements:
-
Statement 1: "The orientation of the figure did not change."
- False: A 90° rotation changes the orientation of the figure.
-
Statement 2: "The corresponding angle measures in the pre-image and image are congruent."
- True: A rotation preserves angles, so the corresponding angles are congruent.
Final Answers:
- The orientation of the figure did change (False).
- The corresponding angle measures are congruent (True).

- How would you rotate a point counterclockwise by 90°?
- Does rotation affect the size of the figure?

- How do reflections differ from rotations?
Tip: Always check how rotations change both the orientation and the coordinates of points systematically.
