Exploring What Makes Triangles Congruent Reteach

If the corresponding parts of triangles are congruent, then the triangles are congruent. In the figure:

∠ A ≅ ∠X

∠ B ≅ ∠Y

∠C ≅ ∠Z

AB ≅ XY

BC ≅ YZ

CA ≅ ZX

Therefore,

+ABC ≅ + XYZ .

In the figure,

+PQR ≅ +STU .

1. If QR ≅ TU , what else must be true about the sides of the triangles?

__________ ≅ __________ __________ ≅ __________ 2. If ∠R ≅ ∠U , what else must be true about the angles of the triangles? __________ ≅ __________ __________ ≅ __________ 3. If m∠P = 20°, what is m∠S?

4. If PQ = 4 cm, what is ST?
