3. What is Congruence of Triangles ?
 In geometry, two figures are congruent if
they have the same shape and size.
 This means that either object can be
repositioned so as to coincide precisely with
the other object.
 More formally, two sets of points are called
congruent if, and only if, one figure can be
transformed into the other.

4. Are we Congruent ?
 Are the following picture congruent ?
 Let’s paste picture 1 on picture 2

5. Am I Congruent to You ?
 The following figures may be identical in content
but they aren't identical in size.
 Fig .1 is slightly larger in size.
Fig.1 Fig.2

6. The first set is equal which is known as congruent.
But the set below is not equal, therefore not congruent.

7. Let’s move on to congruence of
triangles.

8. Find the set of triangles which are
not Congruent.

9. The figures must be equal in either the ---
Measure of the angles
The length of the sides
To make an triangle
congruent the above are
necessary.

10. Conclusion
Triangle ABC and Triangle DEF are congruent.
If two triangles have the
same measure (angles and
sides) they are said to be
congruent.
