**Triangle Rotation Problem**

**Problem:**
Triangle \( \triangle ABC \) is graphed on a plane. If \( \triangle ABC \) is rotated 270° about the origin, what are the coordinates of the image?

**Graph Description:**
The graph shows a coordinate plane with Triangle \( \triangle ABC \) plotted. The coordinates of the vertices before rotation are:
- \( A \) at (1, 6)
- \( B \) at (2, 1)
- \( C \) at (3, 5)

After a 270° rotation about the origin, the new coordinates are:
- \( A' = (-1, 6) \)
- \( B' = (-6, 3) \)
- \( C' = (-1, 3) \)

The graph depicts a right triangle, rotated counterclockwise from its original position. The new position of the triangle is accurately represented on the graph with the vertices marked and connected by lines. The x- and y-axes are labeled and each grid square represents one unit.
