2. What is SSS postulate? SSS postulate is one of the way to prove that two triangles are congruent to each other. SSS is the abbreviation of (side, side, side) and we call side, side, side because SSS postulate is using 3 sides of triangle to prove that is congruent to another triangle.
3. More about SSS postulate I think SSS postulate is one of the easiest way to prove that two triangles are congruent. I think this way because SSS postulate is really simple. For example: ASA postulate says two angles are congruent and one line between these two angles. Or in SAS postulate, two sides are congruent and one angle between them
