Answer:
The Treaty of Guadalupe Hidalgo determined the border and payment terms of the Mexican-American War.
Step-by-step explanation:
The Treaty of Guadalupe Hidalgo is the treaty signed on February 2, 1848, which ended the Mexican-American War.
By this treaty, Mexico ceded a huge territory of 1.36 million km2 to the United States for the sum of 15 million US dollars and was forced to settle more than 3 million dollars in claims made by American citizens against Mexico.
By this treaty, the Mexicans also recognized the incorporation of the Republic of Texas as State of the Union while ceding to it the territories which were located east of the Rio Grande and the 107th meridian which passes through the sources of the river, which the Texans had claimed since their independence.
