Conditions of Triangle

For the pair of triangles shown, state the condition why they are congruent. (write the condition in capital letters without spaces between e.g. SAS, SSS, ASA)

In the following pairs of triangles, find the pairs which are congruent? Also, write the criterion of congruence.

• ΔABD ≡ ΔCDB  by SAS condition

• ΔABD ≡ ΔCDB  by ASA condition

• ΔABD ≡ ΔCBD  by SAS condition

• ΔABD ≡ ΔCBD  by ASA condtion

• Yes, by SSS
