To determine the transformations between triangles ABC, A'B'C', and A''B''C'', let's analyze the points of the triangles and the relationships between them.
-
Triangle ABC:
- A(-4, 5)
- B(-1, 3)
- C(-3, 1)
-
Triangle A'B'C':
- A'(4, 5)
- B'(1, 3)
- C'(3, 1)
-
Triangle A''B''C'':
- A''(1, 0)
- B''(-2, -2)
- C''(0, -4)
Transformations:
-
From Triangle ABC to A'B'C':
- If we compare A to A', B to B', and C to C', we see that A' is the reflection of A across the y-axis (since x-coordinates change sign), B' is also the reflection of B across the y-axis, and C' is the reflection of C across the y-axis. This means that triangle ABC is reflected across the y-axis to obtain triangle A'B'C'.
-
From Triangle A'B'C' to A''B''C'':
- Triangle A''B''C'' has a different arrangement and orientation. To understand how triangle A'B'C' can be transformed into triangle A''B''C'', we observe that A' and A'' appear to have moved down, while B' and B'' as well as C' and C'' have both shifted in various directions on the coordinate plane. The transformation likely involves a combination of reflection across the x-axis and some translation.

Conclusion:
- Triangle ABC to A'B'C' involves a reflection across the y-axis.
- Triangle A'B'C' to A''B''C'' likely involves additional transformations including reflection across the x-axis and translation.
Given these observations, the best description that matches our findings and also confirms the congruency of triangle ABC to triangle A''B''C'' (after reflecting and translating) is as follows:
“Rotation of 90 degrees clockwise and then reflection across the x-axis shows that triangle ABC is congruent to triangle A''B''C''.”
This phrase encapsulates the necessary transformations while confirming the congruency established after the transformations.
