Given: ∠t = ∠u ∠trs = ∠urs based on the given information and the algebraic and geometric properties presented or proven thus far, choose the congruence theorem that could be used to prove the triangles congruent. if it is not possible to prove the triangles are congruent, choose "not possible".

Two triangles are congruent, if there is isometry, which one triangle maps into another, that is, they are congruent, if they have the equal corresponding elements, sides and angles. In order to prove congruence, it is not necessary to know all the elements of these triangles. There are sufficient conditions for congruence, which are given through four rules for the congruence. In this case, we have one side that is equal and two angles that are equal, but it is necessary that both angles that are equal are placed on a side that is equal. Here we have only one angle that is placed on the equal side, while the other is opposite to it. However, in this specific setting, we can conclude that the triangles are congruent based on AAS.

- "the civil rights movements"

- "following the american civil war and abolition of slavery, the united states entered a period known as reconstruction, during which black americans continued to suffer from disenfranchisement, racial segregation, and economic oppression. beginning in the early 1950's, black americans launched a series of major campaigns of civil resistance, emphasizing the need for nonviolent protests and civil disobedience."

"such as the montgomery bus boycott of 1955-56, a campaign launched by rosa parks against the policy of racial segregation of the public transit system in alabama. “sit-ins” became popular across the american south, particularly in greensboro, north carolina, increase national sentiment."

- "the counterculture movement"

- "counterculture began to develop in the united states following the rise of conformity in american culture during the 1950s. by 1963, youth, particularly those of the white middle class, began rejecting the cultural standards and normality of their parents, opting for progressive attitudes instead. the movement gained momentum as the civil rights movement became increasingly successful and as the u.s. military intervention of vietnam began to take a negative turn."

"hippie counterculture moved further into popular culture following the summer of love in 1967 when thousands of people came together in the haight-ashbury neighborhood of san francisco. along with greenwich village in new york city, haight-ashbury became a hub for the counterculture movement."
