Congruence of Triangles By SAS Criteria
Congruence of Triangles By SAS Criteria
Theorem: Two triangles are congruent if two sides and the included angle of one are equal to the corresponding sides and the included angle of the other triangle.
|
Given: Two triangles ABC and DEF such that To Prove: Proof: Place As AB = DE [Given] So vertex B falls on vertex E. Since But AC = DF [ Given] Therefore, C will fall on F. Thus, AC coincides with DF. Now, B falls on E and C falls on F. Therefore, BC coincides with EF. Thus, Hence, by definition of congruence, |

Solution: We have,
[
Similarly,
]
.....(i)
In and
we have
AB = PQ [Given]
[From (i)]
and, BC = QR [Given]
So, by SAS criterion of congruence, we have
Illustration: In the given figure, AC = AE, AB = AD and .Show that BC = DE
Solution: We have,
[Given]
[Adding
to both sides]
Now, in triangles ABC and ADE,
[Given]
[From (i)]
and, [Given]
So, by SAS congruence criterion, we have

Students / Parents Reviews [10]
One of the best institutes to develope a child interest in studies.Provides SST and English knowledge also unlike other institutes. Teachers are co operative and friendly online tests andPPT develope practical knowledge also.
