Question

Suppose there are 2 triangles.It can be proved by SAS congruence. Is it necessary that no other congruence criteria could be applied?I want to ask that to prove 2 Δs congruence, is there only 1 congruence criteria?

Answer 1

Answer:

It depends on Q and what is given to us like which angle or side is equal. Mostly it depends on what is given to us. If we are given that two angles and 3 sides are equal than 1+ congruence criteria can be used. Otherwise I don't think so.

Hope it is of some help.

Answer 2

Answer:

Hay Guys!!!!

No

it's wrong. Other congruence could be SSS, ASA, AAS can be applied. Or if it is right angled triangle then RHS congruence can also be applied

Hope it may help you^_^
