a. What two transformations were completed to move triangle ABC to triangle XYZ? Include the name of the transformation and by how much. Example- it was Rotated by 180 degrees and reflected over line x=y

b. Are the shapes congruent? How do you know?

To provide an accurate response to your question about the transformations from triangle ABC to triangle XYZ, I would need specific details about the position, orientation, and coordinates of both triangles. However, I can guide you on how to identify the transformations and determine congruence.

a. Identifying Transformations: To determine which transformations occurred, you should look at the following:

  • Translation: If triangle ABC has been moved to a different position without rotation or flipping, this is a translation.
  • Rotation: Check if the triangle was turned around a point (often the origin) and by what degree.
  • Reflection: Look for symmetry; if triangle ABC is flipped over a line (like the x-axis or y-axis), this indicates a reflection.
  • Dilation: If the size of the triangle has changed while maintaining shape, that’s a dilation rather than a congruent transformation.

You'd need to calculate or observe the specific amounts for rotation (degrees), directions for reflection, or distances for translation.

b. Are the Shapes Congruent? Two shapes are considered congruent if one can be obtained from the other using rigid transformations (translations, rotations, reflections) that do not change size or shape. If you find that triangle ABC was transformed into triangle XYZ by any combination of these transformations, they are congruent.

Conclusion: Without specific details, you need to analyze the triangles' positions and shapes with this approach in mind to answer the two questions accurately.
