Answer:
SSS(Side Side Side) is finding if all the sides are congruent to another triangle's side
SAS(Side Angle Side) is finding if a side, angle, side are congruent to another triangle's side.
Step-by-step explanation:
1. I will help with problem 7.
2. Two triangles ΔPQR and ΔSTU
3. As you can see sides P and R are the same length as S and U, while P and Q are the same length as T and U. And ∠Q ≈ ∠T.
4. This is proven by SAS- Side - Angle - Side
