Question

Triangle QRS has been translated to create triangle Q'R'S'. RS = R'S' = 2 units, angles S and S' are both 28 degrees, and angles R and R' are both 32 degrees. Which postulate below would prove the two triangles are congruent?

Answer 1

The triangle shares two angles and 1 side : ASA.

Answer 2

If this is a triangle all the angles should equal 180 right. So if you add 32 +28=s and 180- s= the missing angle which will prove weather or not its congruent.
