Can δtsr and δqrs be proven congruent by sas?

yes,   two triangles δtsr and δqrs be proven congruent by sas.

proof 1.→ in δ tsr and δqrs, if these are true

sr is common.

∠1 =∠2

and if , tr =rq

or

sr is common.

∠3=∠4

and if, ts =sq

then the two triangles can be proved congruent,by sas

→δtsr ≅ δqrs   [sas]
