Because in eclipsing binaries, the two stars orbit each other regularly passing in front of the other, blocking out some or all of light of the hidden star.
"Occulting binary". The word "occult" means hidden or in shadows; if a binary star's orbital plane happens to be exactly through the Earth's path, we might see two stars when they're separate and then see one of the stars disappear behind (or in front of) the other.
Each of those is an eclipsing binary.
An eclipsing binary system consists of two stars orbiting each other in such a way that they periodically pass in front of each other as seen from Earth. The light curve of an eclipsing binary system will show regular dips in brightness when one star crosses in front of the other, creating a characteristic pattern of alternating minima and maxima. These dips in brightness are caused by eclipses and can be used to determine various properties of the stars, such as their sizes and masses.
An eclipsing binary star in Perseus is a system where two stars orbit each other in such a way that they periodically pass in front of each other, causing eclipses and variations in brightness as viewed from Earth. By studying these changes in brightness, astronomers can determine important properties of the stars, such as their masses and radii.
Binary stars in eclipsing binaries orbit each other in such a way that from our viewpoint on Earth, they regularly pass in front of each other, causing eclipses. By studying the light curves during these eclipses, astronomers can infer information about the stars' sizes, masses, and orbital dynamics. This makes eclipsing binaries important for understanding stellar properties and evolution.

Yes, because it is easier to determine the precise times of their mutual orbits, which allows us to calculate their masses.
That's an 'eclipsing binary'.

Yes. Zeta Tauri, Kappa Tauri, and Lambda Tauri are eclipsing binary stars.
That happens in an "eclipsing binary".
A binary star consists of two stars gravitationally locked together in a mutual orbit. If the plane of that orbit is in line with us, as observers, then occasionally, one star will eclipse the other, producing a change in luminosity as one star is briefly blocked from view.
Each of those is an eclipsing binary.
Precisely by the eclipse - that's what an "eclipsing binary system" is all about. The idea is that one of the stars partially (or completely, in some cases) covers the other star; with the result that the combined brightness (as seen from Earth) gets less for some time.
Generally the main star as this will have the most mass. However, temperature is not necessarily based on mass, so a secondary unit, could well be hotter but less massive.
It is easy (with the right equipment ) to measure the periodicity of the eclipsing system and thereby the rotational speeds and thereby the relative masses and thereby (with the brightness) the distance and all sorts of other things.
