### 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.
