A triangle has vertices , , and . If the triangle is dilated by a scale factor of through center , what are the image vertices? Draw the preimage and image on the coordinate plane.
- Start with one vertex and multiply each coordinate by the scale factor, .
- Repeat the process with another vertex. Multiply each coordinate of the vertex by the scale factor.
- Repeat the process for the last vertex. Multiply each coordinate of the vertex by the scale factor.
- List the image vertices.
- Draw the preimage and image on the coordinate plane.
