To translate triangle ABC by 3 units to the left and 5 units down, you'll subtract 3 from the x-coordinates of each vertex and subtract 5 from the y-coordinates of each vertex.
Let's denote the original coordinates of the vertices of triangle ABC as:
- A(x1, y1)
- B(x2, y2)
- C(x3, y3)
After the translation, the new coordinates will be:
- A'(x1 - 3, y1 - 5)
- B'(x2 - 3, y2 - 5)
- C'(x3 - 3, y3 - 5)
If you provide the original coordinates of triangle ABC, I can calculate the new coordinates for you.
