Each page has an independent triangle (pre-image) and two dependent triangles (images). Determine which triangle is the independent triangle, and name the coordinate rules that map the independent triangle onto the dependent triangles. Use a composition of transformations.
One of the three triangles is independent, and the other two are dependent. Determine the independent triangle. Identify the type of transformations that map the independent triangle onto the dependent triangles. Write as a coordinate rule as well.
