Math Problem Statement
Solution
The problem involves analyzing the given transformations of rectangle to determine which graphs represent a valid rigid transformation. A rigid transformation preserves the shape and size of the figure, meaning the distances between corresponding points remain the same, and angles are unchanged.
Steps to Analyze:
-
Original Coordinates: From the provided graph of rectangle :
-
Rigid Transformations: Types of rigid transformations include translations, reflections, and rotations. These do not change the size or shape of the rectangle.
-
Verification: Each of the answer options needs to be checked for:
- Preservation of side lengths: The transformed rectangle must have the same dimensions as the original.
- Correct correspondence: Verify each vertex is mapped correctly.
Observations from the Images:
- First Option (Top Left): This appears to be a translation of the original rectangle downward and slightly to the right. All side lengths and orientation are preserved. Valid.
- Second Option (Top Right): This shows a reflection across the -axis. The orientation is flipped, but distances and angles are preserved. Valid.
- Third Option (Bottom Left): This is another rigid transformation, likely a 90° clockwise rotation around a point. Dimensions are preserved. Valid.
- Fourth Option (Bottom Right): This seems to show an incorrect transformation where distances are not preserved, as the rectangle looks stretched or distorted. Not valid.
Final Answer:
The valid transformations are Top Left, Top Right, and Bottom Left.
