Geometry (Proofs): PLEASE HELP!
Write out, in paragraph form, a plan for completing the following proof.
For example, will you prove triangles congruent? How? By what theorem?
Given:
AR = AQ
RT = QS
Prove:
RAT = QAS

Here is the image: https://media.glynlyon.com/o_geo_2009/4/page47a.gif

If it helps I've already figured out:
AS is the median of RT and AT is the median of SQ - definition of median of a triangle.
and
4 and 5, 6 and 7 are supplementary- proved by the definition of supplementary angles.
