$\Delta ABC \sim \Delta PQR$ for the correspondence $ABC \leftrightarrow QRP$. If $m \angle A = 80^{\circ}, m \angle B = 40^{\circ}$ and $m \angle C = 60^{\circ}$,find the measures of all the angles of $\Delta PQR$.

  • A
    $m \angle P = 60^{\circ}, m \angle Q = 80^{\circ}, m \angle R = 40^{\circ}$
  • B
    $m \angle P = 80^{\circ}, m \angle Q = 40^{\circ}, m \angle R = 60^{\circ}$
  • C
    $m \angle P = 40^{\circ}, m \angle Q = 60^{\circ}, m \angle R = 80^{\circ}$
  • D
    $m \angle P = 60^{\circ}, m \angle Q = 40^{\circ}, m \angle R = 80^{\circ}$
