Triangle Congruence Postulates
Skill Practice!
Determine whether △ABC ≅ △KLM given the coordinates of the vertices. Explain.
1. A(–3, 3), B(–1, 3), C(–3, 1), K(1, 4), L(3, 4), M(1, 6) 2. A(–4, –2), B(–4, 1), C(–1, –1), K(0, –2), L(0, 1),
M(4, 1)
3. Write a flow proof.
PR ≅ DE, PT ≅ DF
Given:
∠R ≅ ∠E, ∠T ≅ ∠F
Prove: △PRT ≅ △DEF.
Determine which postulate can be used to prove that the triangles are congruent.
If it is not possible to prove that they are congruent, write not possible.
