(02.01 HC)
Triangle JOY is translated using the rule $ (x, y) \to (x + 3, y - 2) $ to create triangle $ J' O' Y' $. If a line segment is drawn from point $ J $ to point $ J' $ and from point $ O $ to point $ O' $, which statement would best describe the line segments drawn?
a
They share the same midpoints.
b
They create diameters of concentric circles.
c
They are parallel and congruent.
d
They are perpendicular to each other.
1. **State the problem:**
Triangle $JOY$ is translated by the rule $$ (x, y) \to (x + 3, y - 2) $$ to form triangle $J'O'Y'$. We draw line segments from $J$ to $J'$ and from $O$ to $O'$. We need to determine which statement best describes these line segments.
2. **Understand the translation:**
The translation rule moves every point by adding $3$ to the $x$-coordinate and subtracting $2$ from the $y$-coordinate.
3. **Analyze the line segments $JJ'$ and $OO'$:**
- The segment $JJ'$ connects $J(x, y)$ to $J'(x+3, y-2)$.
- The segment $OO'$ connects $O(x, y)$ to $O'(x+3, y-2)$.
4. **Calculate the vector representing these segments:**
The vector from $J$ to $J'$ is $$ \vec{v} = (3, -2) $$.
Similarly, the vector from $O$ to $O'$ is also $$ \vec{v} = (3, -2) $$.
5. **Determine properties of the segments:**
- Both segments have the same direction vector, so they are parallel.
- Both segments have the same length, calculated by $$ \sqrt{3^2 + (-2)^2} = \sqrt{9 + 4} = \sqrt{13} $$, so they are congruent.
6. **Check other options:**
- They do not share midpoints because $J$ and $O$ are different points.
- They do not create diameters of concentric circles; no circles are involved.
- They are not perpendicular because the direction vector is the same for both.
**Final answer:**
**c. They are parallel and congruent.**
