Answer 1

By the congruent rule
SSS - side side side
SAS - side angle side
AAS - angle angle side
RHS - right angle hypotenuse
ASA - angle side angle.
By using this 5 rules we can prove that 2 triangles are congruent.

Answer 2

Answer:

U CAN USE DIFFERENT CRITERION SUCH AS

1. SIDE SIDE SIDE CONGRUENT RULE

             IN THIS ALL THE 3 SIDES ARE SHOWN AS EQUAL

2. SIDE ANGLE SIDE CONGRUENT RULE

              IN THIS 2 SIDES AND THE ANGLE SUBTENDED  BY TEM ARE SHOWN AS EQUAL

3. ANGLE SIDE ANGLE CONGRUENT RULE

               IN THIS 2 ANGLES AND THE SIDE BETWEEN THEM ARE SHOWN EQUAL

4. ANGLE ANGLE ANGLE CONGRUENT RULE

               IN THIS ALL THE ANGLES ARE SHOWN EQUAL

5. RHS CONGRUENCE RULE

IN THIS ONE ANGLE SHOULD BE 90 AND ANY 2 SIDES EQUAL

NOTE : THE SIDES AND ANGLES TAKEN SHOULD BE CORRESPONDING
