sss Postulate
""SSS"" stands for ""side-side-side,"" while a ""postulate"" is something we mathematicians accept as true is true without having to prove it. Let's discover more about the SSS postulate:
The SSS postulate, explained
The SSS postulate states that:
If one triangle's three sides are congruent to another triangle's three sides, then these two triangles are congruent.
Remember, we can use the term "congruence" interchangeably with "equality."
Visualizing the SSS postulate
Let's take a look at what the SSS postulate actually looks like:
We can see that in these two triangles, the sides of one triangle are congruent to the sides of the other. We can put this in a formula:
Side AB ≅ side DE, side BC ≅ side EF, and side AC ≅ DF.
The symbol "≅" represents congruence.
Therefore, ΔABC ≅ ΔDEF.
