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.

i think the answer is c, rivers.

explanation:

sometimes, borders fall along natural boundaries like rivers or mountain ranges. for example, the boundary between france and spain follows the crest of the pyrenees mountains. for part of its length, the boundary between the united states and mexico follows a river called the rio grande. the borders of four countries divide africa’s lake chad: niger, chad, cameroon, and nigeria.
