1) SSS
2) ASA
3) SAS
Step-by-step explanation:
1) Two sides of one triangle corresponds to two sides of the other triangle.
The line joining both triangles is the same (reflexive property)
Hence, three sides of one triangle corresponds to three sides of the other triangle
The congrunececriteria is side-side-side (SSS)
2) Two angles of one triangle corresponds to two angles of the other triangle
The side in between the angles of one triangle corresponds to the side in between the two angles in the other triangle.
The congruence criteria is Angle-side-Angle (ASA)
3) Two sides of one triangle corresponds to two sides of the other triangle.
The angle between the sides of one triangle corresponds to the angle between the sides of the other triangle.
The congruence criteria is side-angle-side (SAS)
