To show that triangles ABC and DEF are congruent by the AAS (Angle-Angle-Side) theorem, you need to establish that two angles and the non-included side of one triangle are congruent to the corresponding two angles and the non-included side of the other triangle. If you have already shown two angles congruent, you would need to prove that one of the sides opposite one of those angles in triangle ABC is congruent to the corresponding side in triangle DEF. This additional information will complete the criteria for applying the AAS theorem.
To determine if triangles ABC and DEF are similar, you would need to check for corresponding angles being congruent or the sides being in proportion. If the angles are congruent (Angle-Angle Postulate) or the sides are in proportion (Side-Side-Side or Side-Angle-Side similarity theorems), then triangles ABC and DEF are similar. Please provide more specific information about the triangles to identify the applicable postulate or theorem.
If triangles ABC and DEF are congruent (ABC ≅ DEF), then corresponding parts of the triangles are congruent by the principle of CPCTC (Corresponding Parts of Congruent Triangles are Congruent). This means that segments AB ≅ DE, BC ≅ EF, and AC ≅ DF, as well as angles ∠A ≅ ∠D, ∠B ≅ ∠E, and ∠C ≅ ∠F. All these congruences must be true if the triangles are indeed congruent.
The "ABC DEF" naming convention does not directly refer to a specific congruence postulate in geometry. However, congruence postulates generally include Side-Side-Side (SSS), Side-Angle-Side (SAS), and Angle-Side-Angle (ASA) among others. To determine which postulate applies, you would need to specify the relationships between the angles and sides of triangles ABC and DEF.
To determine which overlapping triangles are congruent by the Angle-Side-Angle (ASA) postulate, you need to identify two angles and the included side of one triangle that correspond to two angles and the included side of another triangle. If both triangles share a side and have two pairs of equal angles, then they are congruent by ASA. For a specific example, if triangles ABC and DEF share side BC and have ∠A = ∠D and ∠B = ∠E, then triangles ABC and DEF are congruent by ASA.
They are congruent when they have 3 identical dimensions and 3 identical interior angles.
It depends on where and what ABC and DEF are!

false
Answer: Since you are looking for the scale factor of ABC to DEF the answer is 8 because DEF is 8 times larger than ABC.
false
Transitive
If triangles ABC and DEF are congruent (ABC ≅ DEF), then corresponding parts of the triangles are congruent by the principle of CPCTC (Corresponding Parts of Congruent Triangles are Congruent). This means that segments AB ≅ DE, BC ≅ EF, and AC ≅ DF, as well as angles ∠A ≅ ∠D, ∠B ≅ ∠E, and ∠C ≅ ∠F. All these congruences must be true if the triangles are indeed congruent.
ABC
The "ABC DEF" naming convention does not directly refer to a specific congruence postulate in geometry. However, congruence postulates generally include Side-Side-Side (SSS), Side-Angle-Side (SAS), and Angle-Side-Angle (ASA) among others. To determine which postulate applies, you would need to specify the relationships between the angles and sides of triangles ABC and DEF.
False. If ABC definitely equals DEF equals MNO and MNO equals PQR then ABC does not equal PQR by the transitive property.
