3. CONGRUENT
TRIANGLES

5. Real life examples of Congruent
figures
Stack of coins placed one over the
other.
Stack of CD placed over the other.

6. Mathematical examples of
Congruent figures
oTwo circles having the same radii
oTwo triangles with the same
measure.

7. The Theorems in Congruent
Triangle
1. SSS
2. ASA
3. SAS
4. RHS

8. 1. SSS Theorem
If three sides of a one triangle are equal to the
three sides of another triangle then those two
triangles are congruent.

9. 2. ASA Theorem
If one side and two angles of a triangle are equal to
the one side and the two angles on it of another
triangle then those triangles are congruent.

10. 3. SAS Theorem
It two sides and their included angle of one triangle
is equal to the two sides and included angle of
another triangle then they are congruent.

11. 4. R.H.S Theorem
If the base and altitude of a right angled triangle are
equal to the base and altitude of another right angled
triangle then those two triangles are congruent.

12. Are they congruent? Why?
Ans: Yes
By R.H.S
