What planet would have no advantage of any kind over earth for making parallax measurements?
You have to ask yourself what is an advantage when parallax measurements are being made? . . parallax happens when you move to a different place and the object you see look a little different, the closest ones appear to have moved more than the ones that are further away.
In astronomy parallax is created when the Earth is in opposite points of its orbit. Stars that are close appear to have moved a little, relative to the mass of stars that are a long distance away.
Parallax was not observed before the 19th century, and the lack of parallax was always used to 'prove' that the Earth could not possibly be going round the Sun. It was only in the 19th century that parallax was observed, but it was only very tiny movements of the closest stars. It forced people to realise that the stars are incredibly far away and the Earth does go round the Sun after all, so it was extra evidence of the Sun being at the centre of the solar system.
A parallax measurement is easier to make if the baseline is longer, so the answer to your question is that Mercury and Venus have no advantage for making parallax measurements.

How do they know how far is a planet?
Within our solar system, it's really easy to tell each planet's distance from the sun. From Newton's law of gravitation, we realized that the time it takes a planet to revolve around the sun only depends on the planet's distance from the sun, and if we know the distance of one of them, we can figure out all the others. If we watch a planet move through the sky, we can see how long it takes for that one to revolve once around the sun. Then we need to know both the distance and time of one planet, and from that one we can calculate all the others. The one for which we know both the distance from, and time to orbit, the sun, is ... our Earth ! With this information, plus watching another planet to see how long it takes to orbit the sun once, we can calculate how far it is from the sun.
Why would astronomers measure the parallax angle of a planet or star?
Astronomers measure the parallax angle of a planet or star to determine its distance from Earth. By observing the apparent shift in position of the object against the background stars as the Earth orbits the Sun, astronomers can calculate the angle and use it to estimate the object's distance.

How do astronomers determine the distances to other planets within the solar system?
Astronomers determine the distances to other planets within the solar system using a method called parallax. This involves measuring the apparent shift in position of a planet when viewed from different points in Earth's orbit. By comparing these measurements, astronomers can calculate the distance to the planet using trigonometry.

The apparent westward movement of a planet against the background of stars is called?
"Parallax shift". We can't SEE the difference in position of any star as seen from the Earth 6 months later or earlier, but by measuring the very tiny differences in the positions of the more distant stars, we can observe the "parallax" of a star and thus calculate its distance. This only works for stars less than about 300 light years from Earth.
