Question

76. What other information do you need in order to prove the triangles congruent using the SAS CongruencePostulate?AB C DA. ZCBA LCDAB. ABI ADC. ABADD. ZBACE ZDAC

Answer 1

In the given triangles, ABC and ADC it is gven that,

AC is common to both triangles.

According to SAS congruence postulate, two triangles are congruent if two sides and one included angle equals the corresponding two sides and included angle of another triangle.

So, for the triangles ABC and ADC to be congruent,

`\bar{AB}\cong\bar{AD}`

Hence, option C is correct.
