Question

problem 7: (first taught in lesson 28)
in this triangle, select the included and opposite sides for ∠s.
a b c d e
included sides: rq and sq; opposite side: rs

Explanation:

Step1: Recall side - angle relationship

The included sides of an angle in a triangle are the two sides that meet at the vertex of the angle. For $\angle S$, the sides meeting at vertex $S$ are $\overline{RS}$ and $\overline{SQ}$.

Step2: Identify the opposite side

The opposite side of an angle in a triangle is the side that does not have the vertex of the angle as one of its endpoints. For $\angle S$, the side without $S$ as an endpoint is $\overline{RQ}$.

Answer:

Incorrect. The included sides of $\angle S$ are $\overline{RS}$ and $\overline{SQ}$, and the opposite side is $\overline{RQ}$.
