1

A triangle ABC with vertices A(-2, 1), B(1, 3), and C(0, -1) is translated 3 units to the right and 2 units down. Determine the new coordinates of the translated triangle A'B'C'.

2

A rectangle has vertices at P(1, 2), Q(4, 2), R(4, 5), and S(1, 5). If the rectangle is reflected across the y-axis, what are the new coordinates of the vertices P', Q', R', and S'? Explain how the signs of the coordinates change during this transformation.

Exit ticket

Quick comprehension check

Point A has coordinates (5, -3). What are the coordinates of A' if it is reflected across the y-axis? Triangle XYZ has vertices X(1, 2), Y(3, 4), and Z(5, 1). If the triangle is translated 2 units to the left and 3 units up, what are the coordinates of X', Y', and Z'?
