Every angle of every polygon is made by the sides that join to create it.
What is the exact wording of the problem you were given?

anonymous · Answer

It just says "A(n) _(blank_ is an angle of a triangle formed by the two sides that join to create it." I was told by another that it is called an "included angle".

Forgive me for my typing errors.

Yes, you are correct.
This comes up, for example, when you use SAS to prove triangles congruent.
SAS is side-angle-side, and it has to be two sides and the included angle.
