Answer: SSS
Explanation:
Given: In ΔWAS and ΔNOT
WA = NO, AS = OT, SW = TN
By SSS congruence postulate , we have
ΔWAS ≅ ΔNOT
The SSS congruence postulate or side-side-side postulate tells that if all the three sides of a triangle is equal to all the corresponding sides of the other triangle, then both the triangles are congruent.
Hence, SSS is the right abbreviation used for "side-side-side postulate."
