Question

∆ABC is translated 2 units down and 1 unit to the left. Then it is rotated 90° clockwise about the origin to form ∆A′B′C′. Whats the new coordinates?

Answer 1

From the figure given, it is clear that the coordinate points are A(0, 0), B (1, 3) and C (1, 1)

Triangle ABC is translated 2 units down and 1 unit to the left

Then, the new coordinates will be

A' ( -2
