what vocab word would go with this definition: the point in which sides of the angle meet

supp. angles, point of concurrency, incenter of the triangle, vertex of an angle, alternate intererior angles
i think incenter but theres another definition thats throwing me off.

nvm going to stick w/ vertex of an angle lol

Based on the definition provided, the vocab word that would go with it is "vertex of an angle." The vertex of an angle is the exact point where the two sides of the angle meet.

While "incenter of the triangle" generally refers to the point of concurrency where the angle bisectors of a triangle intersect, it does not directly relate to the definition you provided. The other options you mentioned, such as "supplementary angles," "point of concurrency," and "alternate interior angles," are not directly related to the definition of the point where the sides of an angle meet.

Therefore, the correct vocab word in this case is the "vertex of an angle."
