  2. In △ABC\triangle ABC and △DEF\triangle DEF, ∠A=∠D=50∘\angle A = \angle D = 50^\circ and ∠B=∠E=70∘\angle B = \angle E = 70^\circ. Which is true?
  3. Are triangles with sides 3,5,63, 5, 6 and 6,10,136, 10, 13 similar?
  4. △PQR\triangle PQR has PQ=3PQ = 3, PR=5PR = 5, ∠P=40∘\angle P = 40^\circ; △XYZ\triangle XYZ has XY=6XY = 6, XZ=10XZ = 10, ∠X=40∘\angle X = 40^\circ. Are they similar?
