Answer :
Final answer:
Aristotle used the shadow of the Earth during an eclipse and observations of different constellations to support his theory that Earth was not flat.
Explanation:
Aristotle used two main arguments to support his theory that the Earth was not flat:
- The shadow of the Earth during an eclipse, which always appeared round on the Moon, indicating a spherical Earth.
- Observations of different constellations visible in the North and South as travelers moved, suggesting a curved Earth's surface.
Oblate spheroid calculations and Earth's diameter were not specifically mentioned in Aristotle's arguments.
