yes, by sss
yes, by asa
yes, by sas
not enough information

answer !

by SSS rule.      

Step-by-step explanation:

We are given the following information in the question:

We have to prove congruency of two triangles.

In ΔABC and ΔADC

AC = AC (common side)

AB = BC (given)

AD = CC (given)

Hence, by SSS rule of congruence, the two triangles are congruent.

Hence,

Yes, by SSS

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
