Quick comprehension check
“Triangle ABC has vertices A(1, 1), B(3, 1), and C(3, 3). If the triangle is translated 4 units to the left, what are the coordinates of the new vertices A', B', and C'? Point P has coordinates (2, 4). If point P is reflected over the y-axis, what are the coordinates of the new point P'? Rectangle WXYZ has vertices W(1, 0), X(3, 0), Y(3, 2), and Z(1, 2). If the rectangle is rotated 90° counterclockwise around the origin, what are the coordinates of the new vertices W', X', Y', and Z'?”
