Theory:

Let us discuss the different types in the congruence of the triangle. They are:
  • SSS congruence
  • ASA congruence
  • RHS congruence
SSS Congruence: The three sides of one triangle are equal to the three sides of another triangle.

In here the three sides of the first triangle are \(4\) units, \(5\) units and \(7\) units which is congruent to the second triangle whose sides are the same \(4\) units, \(5\) units and \(7\) units respectively.
 
Important!
SSS stands for "side, side, side" it means that we have two triangles with all three sides equal.
