Congruent Triangles

Congruent Triangles

Points to be Remember:-

1. Two figures are congruent, if they have the same shape and size.

2. Two triangles are congruent, if in a matching of their vertices, the

     three sides and the three angles of one triangle are respectively

     equal to the corresponding parts of the other.

3. Two triangles are congruent, if two sides and the included angle of

     the one triangle are respectively equal to the two sides and the

     included angle of the other (SAS congruence condition)

    SSS congruence condition

   Two triangles are congruent, if the three sides of the triangle are

    respectively equal to the three sides of the other. This is called

    SSS congruence condition.

     RHS congruence condition

  Two right triangles are congruent, if the hypotenuse and one side of  

  the one triangle are respectively equal to the hypotenuse and one

  side of the other. This is called RHS congruence condition.
