Transformations Congruence
1. The problem asks to identify corresponding angles after a rotation and verify answers about transformations and congruence.
2. For the rotation of figure KOPQ to KLMN, corresponding angles are those at vertices that map onto each other. Given angle N corresponds to angle P, and angle P corresponds to angle M, the answers are correct.
3. For the reflection of triangle DEF across the x-axis, the coordinates of vertices D, E, F change by negating the y-coordinate:
- D(−2, 5) reflects to D'(−2, −5)
- E(−3, 2) reflects to E'(−3, −2)
- F(−6, 4) reflects to F'(−6, −4)
These match the given coordinates, so the reflection is correct.
4. For the translation of figure TUVW to T'U'V'W', each x-coordinate decreases by 4 while y-coordinates remain the same, indicating a translation 4 units to the left.
5. Figures G and K are transformations of figure 1 that preserve parallel sides, confirming the correct choice.
6. For congruence of figures R and L:
- Translate R 1 unit left, then rotate 180° clockwise: Yes, congruent.
- Rotate R 180° counterclockwise, then translate 1 unit down: No, does not match L.
- Reflect R across x-axis, then rotate 90° counterclockwise: No, does not match L.
- Rotate R 90° counterclockwise, then reflect across y-axis: Yes, congruent.
Final answers:
- Corresponding angles: N and P, P and M.
- Reflection coordinates: D'(−2, −5), E'(−3, −2), F'(−6, −4).
- Translation: 4 units left.
- Figures showing parallel sides preserved: G and K.
- Congruence sequences: Yes, No, No, Yes.
