Final answer:
To translate the triangle with the given vector -1,3, each vertex's coordinates are adjusted accordingly. The new vertices of the translated triangle are A'(2,7), B'(1,2), and C'(3,15).
Step-by-step explanation:
To translate a triangle along a given vector, we add the vector components to each vertex of the triangle. Given the vector -1, 3 and the vertices A(3,4), B(2,-1), C(4,12), we calculate the new coordinates:
- A' = (3 - 1, 4 + 3) = (2, 7)
- B' = (2 - 1, -1 + 3) = (1, 2)
- C' = (4 - 1, 12 + 3) = (3, 15)
The translated triangle has vertices at A'(2,7), B'(1,2), and C'(3,15).
