Question

    The following propositions aretrue or false?

1. Iftwo triangles have all their sides congruent, then they arecongruent       T         F

2. Iftwo triangles have two angles congruent one-to-one,

           then they arecongruent                                                                                T          F

3. Iftwo triangles are congruent, then they aresimilar                                    T          F

4. Iftwo triangles are similar, then they arecongruent                                     T         F

5. Iftwo triangles have two sides congruent one-to-one and oneangle,

           then the triangles arecongruent                                                                    T          F

6. Iftwo triangles have two angles congruent one-to-one,

      thenthey aresimilar                                                                                      T          F

7. Iftwo triangles have one side congruent and two angles congruent

     one-to-one, then they arecongruent                                                             T          F

8. Iftwo triangles have one angle congruent and the ratios of thesides

      ofthis angle are equal, then the triangles arecongruent.                              T         F
