The shadowed portion is entirely hidden from view. The first quarter and third quarter moons (both often called a half moon), happen when the moon is at a 90 degree angle with respect to the earth and sun. So we are seeing exactly half of the moon illuminated and half in shadow.
total lunar: moon goes all the way into the umbra of the earths shadow. Partial lunar: moon goes partway into the earths shadow umbra. Penumbral Lunar: the moon goes into the penumbra. Total Solar: the umbra of the moon passes over the earth. Partial Solar: Center of the moons shadow never passes over the earth. Annular: Center of the moon's shadow passes over the earth but the umbra ends before reaching the earth. Hybrid Solar: Eclipse starts as an annular, the umbra isn't reaching the earth.
