4.6. SSS Triangle Congruence http://www.ck12.org


Find the lengths of the sides of each triangle to see if the two triangles are congruent.


8.


9.



  1. 4 ABC:A(− 1 , 5 ),B(− 4 , 2 ),C( 2 ,− 2 )and 4 DEF:D( 7 ,− 5 ),E( 4 , 2 ),F( 8 ,− 9 )

  2. 4 ABC:A(− 8 ,− 3 ),B(− 2 ,− 4 ),C(− 5 ,− 9 )and 4 DEF:D(− 7 , 2 ),E(− 1 , 3 ),F(− 4 , 8 )

  3. 4 ABC:A( 0 , 5 ),B( 3 , 2 ),C( 1 , 4 )and 4 DEF:D( 1 , 2 ),E( 4 , 4 ),F( 7 , 1 )

  4. 4 ABC:A( 1 , 7 ),B( 2 , 2 ),C( 4 , 6 )and 4 DEF:D( 4 , 10 ),E( 5 , 5 ),F( 7 , 9 )

  5. Draw an example to show why SS is not enough to prove that two triangles are congruent.

  6. If you know that two triangles are similar, how many pairs of corresponding sides do you need to know are
    congruent in order to know that the triangles are congruent?
