What constellations do Cowherd and Weaver Girl belong to respectively?

Hello, China people told the story of Cowherd and Weaver Girl in 2000. Today, however, people often talk about them, but they rarely find this pair of people looking for marriage in heaven. They are on summer nights in the northern hemisphere, on both sides of the Milky Way. The apparent magnitude of Altair is 0.77, which is the first 12 bright star in the whole day. Vega's apparent magnitude is 0.03, which is the fifth brightest star in the whole day and the second brightest star north of the celestial equator.

2 1 century, in modern astronomy, Altair is called Alpha Lyra, Vega is called Alpha Lyra, and the star is called Cygnus, which is an attachment from the Greeks. At the same time, looking up at the starry sky in the northern hemisphere in summer, you can see the morning glory, the Weaver Girl and the alpha star Tianjin IV in Cygnus, forming an eye-catching triangle, which is the famous "Summer Triangle". Thank you.
