Final answer:
To prove triangle ABC congruent to triangle DEF using ASA, we need the measures of angles A and D as well as the length of another side.
Step-by-step explanation:
In order to prove that triangle ABC is congruent to triangle DEF using the ASA (Angle-Side-Angle) congruence postulate, we would need the following additional information:
- The measure of angle A in triangle ABC
- The measure of angle D in triangle DEF
- The length of another side in triangle ABC or triangle DEF
With these additional pieces of information, we can compare the corresponding angles and sides of the two triangles to determine if they are congruent.
