Math Problem Statement
Solution
The graph shows two triangles, and its transformed version , on a coordinate plane. Based on the graph, it appears that has undergone a transformation to form .
Observations:
- The points and are overlapping with , suggesting that there was a reflection or rotation involved.
- Both triangles seem to be congruent, indicating that the transformation preserves size, meaning it could involve reflections, rotations, or translations.
Answer:
The transformation from to is a reflection over the y-axis. This is evidenced by the symmetry of the triangles across the y-axis and the corresponding vertices' mirrored positions.
Would you like a more detailed explanation or have any questions? Here are 5 related questions you might be interested in:
- What are the rules for reflecting points across the y-axis?
- How can you verify if a transformation is a reflection, rotation, or translation?
- How do congruent triangles behave under different transformations?
- What are other common types of geometric transformations?
- How can we mathematically describe reflections in the coordinate plane?
Tip: When reflecting over the y-axis, the x-coordinates of points change sign, but the y-coordinates remain the same.
