The isosceles triangle theorem says "If two sides of a triangle are congruent, then the angles opposite those sides are congruent."

If you are using this figure to prove the isosceles triangle theorem, which of the following would be the best strategy?
A. Draw QS so that S is the midpoint of PR, then prove PQS RQS using SSS.
B. Draw QS bisecting Q, with S on PR, then prove PQS RQS using ASA.
C. Draw QS bisecting Q, with S on PR, then prove PQS RQS using AAS.
D. Draw QS so that S is the midpoint of PR, then prove PQS RQS using SAS.
