1. CONGRUENT TRIANGLE BY S. RAMANI

2. LOOK AT THE FOLLOWINGFIGURES

4. WHAT IS CONGRUENT FIGURE ?

5. FIGURES HAVING SAME SIZE AND SAME SHAPE ARE SAID TO BE CONGRUENT FIGURES

6. TO DEFINE CONGRUENT TRIANGLES WHAT ARE ALL REQUIRED?

7. 1.CONGRUENT LINES 2. CONGRUENT ANGLES WHY DO WE NEED ONLY THESE TWO?

8. SINCE TRIANGLES ARE MADE UP OF LINES AND ANGLES. WHEN DO YOU SAY TWO LINES ARE CONGRUENT?---WHY? WHEN DO YOU SAY TWO ANGLES ARE CONGRUENT?--WHY?

9. TWO LINES ARE CONGRUENT IF THEY ARE OF IN SAME LENGTH

10. TWO ANGLES ARE CONGRUENT IF THE ARMS OF ONE ANGLE CONCIDE WITH THE ARMS OF OTHER ANGLE

12. WE TWO WHEN DO TRIANGLES ARE CONGRUENT?

13. TWO TRIANGLES ARE SAID TO BE CONGRUENT IF WE SUPER IMPOSE ONE TRIANGLE ON THE OTHER IT MUST COINCIDE EACH OTHER

15. WHEN TWO TRILANGLES ARE CONGRUENT WHAT ARE ALL CAN BE OBSERVED?

16. 1.THE SIDES ARE FOUND TO BE EQUAL 2.THE ANGLES ARE FOUND TO BE EQUAL

17. IDENTIFY THE SIDES ARE EQUAL AND THE ANGLES ARE EQUAL.

18. HOW MANY MATCHING PARTS FOUND ARE EQUAL? THERE ARE SIX GIVE FEW TRIANGLES TO IDENTIFY THE MATCHING PARTS ARE EQUAL

19. IS IT NECESSARY TO HAVE 6 MATCHING PARTS EQUAL TO DEFINE TWO TRIANGLES ARE CONGRUENT?

20. NO THEN HOW MANY? IF POSSIBLE WITH LESS THAN 6 WHAT ARE THEY?

21. WHAT IS THE THEOREM?

22. SAS CONGRUENT THEOREM IF TWO SIDES AND AN ANGLE BETWEEN THE SIDES ONE TRIANGLE CORRESPONDINGLY EQUAL TO TWO SIDES AND AN ANGLE BETWEEN THE SIDES OTHER TRIANGLE, THEN THE TRIANGLES ARE CONGRUENT
