To reflect the triangle ABC across the x-axis and the y-axis, we can follow these steps:
- Reflect across the x-axis: This changes the y-coordinates of each vertex to their negatives.
- Reflect across the y-axis: This changes the x-coordinates of each vertex to their negatives.
Let's apply these transformations to each vertex of triangle ABC:
Original Vertices:
- A = (2, -1)
- B = (6, -3)
- C = (1, -3)
Step 1: Reflect across the x-axis:
- A: (2, -(-1)) = (2, 1)
- B: (6, -(-3)) = (6, 3)
- C: (1, -(-3)) = (1, 3)
Step 2: Reflect across the y-axis:
- A': (-2, 1)
- B': (-6, 3)
- C': (-1, 3)
Thus, the vertices of triangle A'B'C' after both reflections are:
- A' = (-2, 1)
- B' = (-6, 3)
- C' = (-1, 3)
The correct response is: The vertices of triangle A′B′C′ are A′(−2,1), B′(−6,3), and C′(−1,3).
