2. It is to be established by RHS congruence rule that . What additional information is needed, if it is given that
To prove congruency by RHS (Right angle, Hypotenuse, Side ) rule, we need hypotenuse and side equal to the corresponding hypotenus and side of different angle.
( Right angle )
( Side )
So the third information we need is the equality of Hypotenuse of both triangles. i.e.
Hence, if this information is given then we can say,
