Math Problem Statement

What is the transformation from triangle ABC to triangle A'B'C'?

Solution

The graph shows two triangles, ABC\triangle ABC and its transformed version ABC\triangle A'B'C', on a coordinate plane. Based on the graph, it appears that ABC\triangle ABC has undergone a transformation to form ABC\triangle A'B'C'.

Observations:

  • The points AA and CC are overlapping with A=CA' = C', 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 ABC\triangle ABC to ABC\triangle A'B'C' 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.

  3. How do congruent triangles behave under different transformations?
  4. What are other common types of geometric transformations?
  5. 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.
