riangle ABC has vertices A(−3, 1), B(−3, 4), and C(−7, 1). If ∆ABC is translated according to the rule (x, y) → (x − 4, y + 3) to form ∆A′B′C′, how is the translation described with words? (3 points) Where are the vertices of ∆A′B′C′ located? Show your work or explain your steps. (4 points) Triangle A′B′C′ is rotated 90° clockwise about the origin to form ∆A″B″C″. Is ∆ABC congruent to ∆A″B″C″? Give details to support your answer. (3 points)
