Yes, the image appears to show the result of a 180° counterclockwise rotation about the origin, and the orange triangle seems to be the image of the green triangle after this transformation. Let's check the vertices to confirm this.

The original vertices of the green triangle are:

• $(1, 3)$
• $(2, 1)$
• $(3, 2)$

For a 180° rotation about the origin, the rule is: $(x, y) \rightarrow (-x, -y)$

Applying this rule to the vertices:

• $(1, 3) \rightarrow (-1, -3)$
• $(2, 1) \rightarrow (-2, -1)$
• $(3, 2) \rightarrow (-3, -2)$

Now, let's compare these results with the coordinates of the orange triangle's vertices from the image:

• $(-2.1, -0.9)$
• $(-3.2, -1.9)$
• $(-0.9, -3)$

These points are quite close to the expected rotated coordinates, considering possible rounding in the image software. Therefore, it looks correct overall.
