The SAS Congruence Theorem states that if two triangles have one pair of congruent sides and the included angle (the angle between the two sides) is also congruent, then the two triangles are congruent.
So, the correct response from your list would be:
If two triangles have one pair of congruent sides and the included angle between those sides is congruent, then the triangles are congruent.
However, none of the responses provided perfectly articulate the SAS Congruence Theorem accurately. The closest match would be the second option, with some modification for accuracy:
- If two triangles have two pairs of congruent sides and the included angle is congruent, then the triangles are congruent.
