Answer:

The coordinates of the vertices of the triangle ABC after a rotation of 180 degrees about the origin are:

A'(-2,0), B'(1,-5), and C'(-4,-3).

Explanation:

To determine the coordinates of the vertices of the triangle ABC after a rotation of 180 degrees about the origin, we can use the following transformation rules:

For a rotation of 180 degrees about the origin:

- The x-coordinate becomes its negative counterpart.

- The y-coordinate becomes its negative counterpart.

Let's apply these rules to each vertex of the triangle:

Vertex A(2,0):

- The x-coordinate becomes -2.

- The y-coordinate remains 0.

Therefore, after the rotation, vertex A becomes A'(-2,0).

Vertex B(-1,5):

- The x-coordinate becomes 1.

- The y-coordinate becomes -5.

Therefore, after the rotation, vertex B becomes B'(1,-5).

Vertex C(4,3):

- The x-coordinate becomes -4.

- The y-coordinate becomes -3.

Therefore, after the rotation, vertex C becomes C'(-4,-3).
