Answer: SSS
Explanation:
Given : Triangle MOP has been rotated to create triangle M'O'P'.
such that MP = M'P' = 2 units
MO = M'O' = 2 units
OP = O'P' = 2.82 units.
Then , by SSS postulate of congruence , we have

- The SSS postulate of congruence says that if three sides of a triangle are congruent to three sides of any other triangle then the triangles are congruent.
