The problem involves matching geometric transformations—reflection across the x-axis, reflection across the y-axis, dilation, and translation—with the resulting vertices of a triangle after applying each transformation. Although the initial vertices of triangle XYZ are not explicitly provided in the question, the key is to understand how each transformation affects the coordinates of the vertices and to determine which set of resulting coordinates corresponds to each transformation based on the given options.

Understanding the Transformations

Transformations in coordinate geometry modify the position of points in specific ways:

  • Reflection across the x-axis: Reflects points over the x-axis, which alters the y-coordinate's sign while leaving the x-coordinate unchanged. For a point (x, y), the reflected point is (x, -y).
  • Reflection across the y-axis: Reflects points over the y-axis, altering the x-coordinate's sign, transforming (x, y) into (-x, y).
  • Dilation with a factor of 3: Enlarges or reduces the size of the figure relative to the origin, multiplying the coordinates of each vertex by 3, so (x, y) becomes (3x, 3y).
  • Translation by a rule: Shifts the entire figure by adding specific values to the x and y coordinates of each vertex. For example, adding (a, b) to each point transforms (x, y) into (x + a, y + b).

Analyzing the Given Data

The options provided for the transformed vertices are:

  1. X’(0,1), Y’(6,3), Z’(2,5)
  2. X’(0, -1), Y’( -6, -3), Z’( -2, -5)

Considering the potential transformations:

  • Reflection across the x-axis:
  • If the original points are reflected across the x-axis, the x-coordinates remain the same, and the y-coordinates are negated. Comparing the two options, the set with y-values negated resembles a reflection across the x-axis.
  • Reflection across the y-axis:
  • In contrast, the set with x-values negated resembles a y-axis reflection.
  • Dilation by a factor of 3:
  • Applying a dilation to the original vertices would multiply each coordinate by 3. To verify, dividing the given transformed vertices by 3 should recover the original vertices if the original points are known.
  • Translation:
  • For the translation, the change in points is consistent with adding or subtracting specific values. For example, if the original vertices are known, applying the translation rule would produce the given points.

Matching Transformations to Vertex Sets

Based on the data, the set of vertices:

X’(0,1), Y’(6,3), Z’(2,5)

appears to be the result of a translation, as these points seem shifted by a constant amount from some original vertices. Conversely, the set with negative y-values,

X’(0, -1), Y’( -6, -3), Z’( -2, -5)

suggests reflection across the x-axis or y-axis, depending on the original points.

Conclusion

Without the explicit original vertices, exact matching is limited. However, based on the nature of the transformations and the options provided:

  • The set X’(0,1), Y’(6,3), Z’(2,5) is most likely the result of a translation.
  • The set X’(0, -1), Y’( -6, -3), Z’( -2, -5) is most consistent with a reflection across the x-axis or y-axis, with the precise identification depending on the original figure.
  • The dilation by a factor of 3 would produce larger shifted points if the original vertices are known.

This analysis demonstrates the importance of understanding how transformations affect coordinates and how to interpret given transformed vertices to identify the applied transformation.
