Question

1 multiple choice 5 points
two triangles are congruent if
the angles in each triangle have a sum of 180°
corresponding sides are proportional
corresponding sides and corresponding angles are congruent
corresponding angles are congruent
2

Explanation:

• The sum of angles in any triangle is \(180^{\circ}\), which is a general property, not a congruence criterion.
• Corresponding sides being proportional is a similarity criterion, not congruence.
• Corresponding angles being congruent is a similarity criterion (if angles are congruent, triangles are similar, not necessarily congruent).
• For two triangles to be congruent, corresponding sides and corresponding angles must be congruent (by the definition of congruent triangles).

Answer:

corresponding sides and corresponding angles are congruent
