triangle congruence are of four types
ASA.. angle side angle
SSS.. side side side
SAS.. side angle side
RHS.. right angle hypotenuse side
If.. you know these four.. u can solve the problem easily..

bt it's very difficult because teachers twist the question
I know... You need to find out these properties between then.. then you can easily find answers

For a triangle to be congruent there are some theorems that are to be remembered
1) SAS test - (Side angle side) test. In this test, check whether two sides of both the triangles are same or not. If yes then the triangles will be congruent by SAS test
2) SSS test - (Side side side) test. In this if all the sides are of same length then they are congruent by SSS test
3)ASA test - (Angle side angle) test. In this if two angles and a side are equal then they are congruent by ASA test
4)RHS test - This test is only applicable for right angled triangles. In this test if a side, hypotenuse and any angle (other than 90) are equal then the triangles are congruent
