Explanation:

These questions are about historical events and timelines related to Texas and U.S. history. To answer them, one would need knowledge of historical facts:

1. For the first question, Sam Houston served two terms as president of the Republic of Texas, with terms (for example, relevant years in the Republic of Texas context).
2. Texas existed as an independent republic from 1836 to 1845, so calculating the difference (1845 - 1836 = 9 years).
3. The annexation of Texas by the United States (or the Treaty of Annexation) officially ended the Republic of Texas when Texas became a U.S. state in 1845.
4. The annexation of Texas led to conflict between the U.S. and Mexico, as Mexico still considered Texas part of its territory.
5. The Treaty of Guadalupe Hidalgo (ending the Mexican - American War) helped secure Texas's southern border by establishing the Rio Grande as the border.
6. Between 1836 and 1848, Texas changed from an independent republic (1836 - 1845) to a U.S. state (1845), and after the Mexican - American War (1846 - 1848), its southern border was solidified, and its territory was confirmed.

Answer:

1. Sam Houston served two terms as the president of the Republic of Texas. His first term was from 1836 to 1838, and his second term was from 1841 to 1844.
2. Texas existed as an independent republic for 9 years (from 1836 to 1845).
3. The annexation of Texas by the United States (when Texas became the 28th state of the United States in 1845) officially ended the Republic of Texas.
4. The annexation of Texas by the United States led to conflict between the United States and Mexico.
5. The Treaty of Guadalupe Hidalgo (which ended the Mexican - American War in 1848) helped secure Texas's southern border.
6. Between 1836 and 1848, Texas transitioned from an independent republic to a U.S. state in 1845. Then, the Mexican - American War (1846 - 1848) resulted in the Treaty of Guadalupe Hidalgo, which solidified Texas's southern border at the Rio Grande and confirmed its territorial boundaries.
