Triangle XYZ, with vertices X(-2, 0), Y(-2, -1), and Z(-5, -2), undergoes a transformation to form triangle X?Y?Z?, with vertices X?(4, -2), Y?(4, -3), and Z?(1, -4). The type of transformation that triangle XYZ undergoes is a . Triangle X?Y?Z? then undergoes a transformation to form triangle X?Y?Z?, with vertices X?(4, 2), Y?(4, 3), and Z?(1, 4). The type of transformation that triangle X?Y?Z? undergoes is a .
