1. Consider the transformations below. Which transformations preserve distance? Which transformations preserve angle measure? Use your knowledge of rigid transformations to compare and contrast congruency and similarity. 1. Translation II. Reflection III. Rotation IV. Dilation 2. if triangle ABC ~ triangle LMN and triangle LMN ~ triangle XYZ is triangle ABC ~ triangle XYZ use the AA similarity criterion to support your answer. 3. suppose that a line that appears parallel to side BC of triangle ABC intersects sides AB and AC at points X and Y respectivily, and AX/AB =1/2. How can you determine if the line is or is not parallel to line BC? Explain.​
