Use the Smith chart to find the normalized input impedance of a lossless line of length l

Question:

Use the Smith chart to find the normalized input impedance of a lossless line of length l terminated in a normalized load impedance zL for each of the following combinations: (a) l = 0.25λ, zL = 1 + j0,
(b) l = 0.5λ, zL = 1+ j1,
(c) l = 0.3λ, zL = 1 - j1,
(d) l =1.2λ, zL = 0.5 - j0.5,
(e) l = 0.1λ, zL = 0 (short circuit),
(f) l = 0.4λ, zL = j3,
(g) l = 0.2λ,
zL = ∞ (open circuit).
