Triangles T S R and Q R S overlap at point P. Angle S T R is 66 degrees and angle S Q R is 66 degrees. The lengths of T S and Q R are both 5 inches. Can ΔTSR and ΔQRS be proven congruent by SAS? yes, because along with the given information on the diagram, SR ≅ RS by the reflexive property yes, because a reflection will map ΔTSR onto ΔQRS yes, because P appears to be the midpoint of SQ and TR no, because not enough is information given to prove the triangles congruent by SAS
