State SSS congruency rule.

State SAS congruency rule.

State ASA congruency rule.

State RHS congruency rule.

Through construction we have seeri that SSS congruency rule hold. This theorem can be proved using a suitable construction.

Prove that triangleAOB~=triangleCOD by using SAS congruency rule.

When do you say that triangleABC ~= triangleDEF ? (Use S.S.S. congruent rule).

Decide whether the SSS congruence is true with the following figures. Give reasons

Given below are measurements of some parts of two triangles. Examine whether the two triangles are congruent or not, using RHS congruence rule. {:(" "Delta ABC ," " Delta PQR ),(angle A = 90^(@) " ,AC = 5 cm, BC = 9 cm " ,angle Q = 90^(@) ", RP= 8 cm, PQ = 5 cm "):}

triangleABC~=triangle DBCby which congruency rule?
