Why would Ptolemy not explain venus phases
Galileo's telescopic observations of the 4 large moons of Jupiter and the phases of Venus helped support the heliocentric model of the solar system developed by Copernicus. Copernicus predicted that all phases would be visible since the orbit of Venus around the Sun would cause its illuminated hemisphere to face the Earth when it was on the opposite side of the Sun and to face away from the Earth when it was on the Earth-side of the Sun. In contrast, the geocentric model of Ptolemy predicted that only crescent and new phases would be seen since Venus was thought to remain between the Sun and Earth during its orbit around the Earth. Galileo's observations of the phases of Venus proved that it orbited the Sun and lent support to (but did not prove) the heliocentric model.
I think that it is because Tycho thought that the sun and the moon orbited Earth but the rest of the planets orbited the sun So this means that from our perspective if tycho was true then the phases of Venus would look different Its not a very technical answer sorry so it could do with improving
If our Earth was the center of our solar system, then Venus would not have phases, like our Moon. If, instead, our Sun was the center, then Venus would show phases. Galileo Galilei showed that Venus did, indeed, have phases.
This means it eats insects, such as a venus fly-trap

Both Mercury and Venus, being closer to the sun than us, will show phases. When Venus is at is brightest it is generally just a bit over half full. If you were on Mars, you would note phases on earth.

There are none. The planet Venus is often seen in its gibbous and crescent phases, but never appears to be full; when it would be, Venus is hidden behind the Sun. And Venus only appears in the "new" phase twice per century, during the "transits of Venus". The planets Mars, Jupiter and Saturn appear in the gibbous and full phases, but never in the crescent or new phases.

Only partly. We never see Mars in a crescent or new phase, just the full and gibbous phases. That's because Mars is farther away from the Sun than the Earth is, so we never see it "inside" our orbit. On the other hand, we see the crescent and gibbous phases of the planet Venus, but never the full or new phases, because when Venus would be "new", it's too close to the Sun to be observed - and when Venus would be "full", it's on the other side of the Sun, and not visible!
Galileo was able to observe Venus going through a full set of phases, something prohibited by the Ptolemaic system (which would never allow Venus to be fully lit from the perspective of the Earth or more than semi-circular). This observation essentially ruled out the Ptolemaic system, and was compatible only with the Copernican system and the Tychonic system and other geoheliocentric models such as the Capellan and Riccioli's extended Capellan model.
The Scientific Revolution started because current scientific theories would not explain what the Egyptian astronomer Ptolemy found. This lead to the advancement of a Scientific Revolution to study of his ideas.
Copernicus and later Galileo and Kepler. Venus was found to have phases Jupiter was found to have moons Elliptical orbits which Kepler found would later be described by gravity Start there.

Ptolemy would have made his observations in Egypt probably Alexandria around AD120 up to his death in AD168.
