Theorem 7.4 (SSS congruence rule) : If three sides of one triangle are equal tothe three sides of another triangle, then the two triangles are congruent. |
|
Answer» If all the three sides of one triangle are equivalent to the corresponding three sides of the second triangle, then the two triangles are said to be congruent by SSS rule. In above given figure, AB= PQ, QR= BC and AC=PR, hence ∆ ABC ≅ ∆ PQR. |
