Since the triangles are rotated around the origin, the distances from the origin to each vertex of triangle DEF remain the same in triangle D'E'F'.
Therefore, the perimeter of triangle D'E'F' is also 24 inches.
Triangle DEF is rotated 90 degrees clockwise around the origin to create triangle D'E'F'.
If the perimeter of triangle DEF is 24 inches, how many inches is the perimeter of triangle D'E'F'?
