A. Determine whether group A or group B (or both) show a pair of similar triangles or not. Tell how you know this.
b. For the group(s) with similar triangles, calculate all unknown side lengths. If possible, calculate the unknown angles. Explain your answers.
c. For the group(s) with similar triangles, calculate the scale factor. What is the relationship of the area of the original figure to the area of the translated figure? Explain.
d. For the group(s) with similar triangles, tell (roughly) what transformations would be needed to make one of the triangles carry onto the other triangle in its group.
