Question

1. translation: 3 units down

Explanation:

Step1: Recall translation rule

For a translation of 3 units down, we subtract 3 from the y - coordinates of each point of the triangle.

Step2: Assume coordinates of points

Let the coordinates of points \(Q(x_1,y_1)\), \(U(x_2,y_2)\), \(L(x_3,y_3)\) of the original triangle. The new coordinates after translation will be \(Q'(x_1,y_1 - 3)\), \(U'(x_2,y_2 - 3)\), \(L'(x_3,y_3 - 3)\).

Answer:

The new triangle is obtained by subtracting 3 from the y - coordinates of all vertices of the original triangle.
