Answer 1

There are 4 categories.
SAS
SSS
ASA
AAS

Answer 2

triangles can be congruent by:
1.S-S-S
2.A-A-S
3.S-A-S
in detail:- suppose triangle ABC and triangle DEF r given then,(1) If AB=DE,BC=EF,AC=DF,then two triangles is said to congruent by SSS criterion.
(2)if anyone two angles suppose angleA=angleD,angleB=angleE,and anyone side suppose AC=DF,then that two triangles is said to be congruent by A-A-S.
(3)if any two sides and anyone angle r equal in two triangles i.e,angleC=angleF,angleE=angleB,AC=DF,then both triangles r said to be congruent by S-A-S criterion.
