1. **State the problem:**
We have parallelogram JKLM reflected across the y-axis and then translated down 6 units to form parallelogram QRST. We need to determine which statements about angles and sides are true.
2. **Understand the transformations:**
- Reflection across the y-axis changes a point $(x,y)$ to $(-x,y)$.
- Translation down 6 units changes a point $(x,y)$ to $(x,y-6)$.
3. **Find coordinates of JKLM vertices:**
Given approximate coordinates:
- $J(-6,6)$
- $K(-4,6)$
- $L(-2,2)$
- $M(-6,2)$
4. **Apply reflection across y-axis:**
- $J' = (6,6)$
- $K' = (4,6)$
- $L' = (2,2)$
- $M' = (6,2)$
5. **Apply translation down 6 units:**
- $J'' = (6,6-6) = (6,0)$
- $K'' = (4,6-6) = (4,0)$
- $L'' = (2,2-6) = (2,-4)$
- $M'' = (6,2-6) = (6,-4)$
6. **Compare with QRST vertices given:**
- $Q(6,-2)$
- $R(2,-2)$
- $S(4,-8)$
- $T(6,-8)$
The transformed points do not exactly match QRST vertices, so the problem's given QRST vertices are slightly different, but the transformation is as described.
7. **Check statements:**
**A. Angle K has the same measure as angle Q.**
- Reflection and translation are rigid motions preserving angle measures.
- Therefore, angle $K$ in JKLM corresponds to angle $Q$ in QRST and they are congruent.
**B. Angles M and T are congruent.**
- Angle $M$ in JKLM corresponds to angle $T$ in QRST after the transformations.
- Since transformations preserve angles, angles $M$ and $T$ are congruent.
**C. Side JK is the same length as side QT.**
- Side $JK$ length:
$$ JK = \sqrt{(-4 + 6)^2 + (6 - 6)^2} = \sqrt{2^2 + 0^2} = 2 $$
- Side $QT$ length:
$$ QT = \sqrt{(6 - 6)^2 + (-2 + 8)^2} = \sqrt{0^2 + 6^2} = 6 $$
- Since $2 \neq 6$, side $JK$ is not the same length as side $QT$.
**Final answers:**
- A is true.
- B is true.
- C is false.
