To determine if triangles PQR and XYZ are congruent, we need to compare their corresponding sides and angles. If all three pairs of sides are equal (SSS), or if two pairs of sides and the included angle are equal (SAS), or if two angles and the corresponding side between them are equal (ASA or AAS), then the triangles are congruent. Additionally, if the triangles are similar (AA), they may not be congruent unless their corresponding sides are also proportional. Thus, without specific measurements or angles provided, we cannot definitively conclude congruence.

That's not a postulate. It's a theorem. And you have stated it.
To verify that two triangles are similar, you can use several similarity postulates and theorems. The most common ones include: **AA Similarity Postulate (Angle-Angle Similarity Postulate):** If two angles of one triangle are congruent to two angles of another triangle, then the two triangles are similar. This postulate relies on the similarity of corresponding angles. **SAS Similarity Theorem (Side-Angle-Side Similarity Theorem):** If two pairs of corresponding sides of two triangles are in proportion, and their included angles are congruent, then the two triangles are similar. This theorem involves both sides and angles. **SSS Similarity Theorem (Side-Side-Side Similarity Theorem):** If the corresponding sides of two triangles are in proportion, then the two triangles are similar. This theorem only considers the proportions of the sides. These postulates and theorems are fundamental principles of triangle similarity and are used to establish whether two triangles are indeed similar. Remember that similarity means that the corresponding angles are equal, and the corresponding sides are in proportion.
Yes, triangle SAM is congruent to triangle DEL if the corresponding sides and angles are equal. This can be established using the Side-Angle-Side (SAS) Congruence Postulate, which states that if two sides of one triangle are proportional to two sides of another triangle and the included angles are equal, then the triangles are congruent. Alternatively, if all three sides of both triangles are equal, the Side-Side-Side (SSS) Congruence Theorem can also be applied.
None; because there is no justification for assuming that the two triangles (or trangles, as you prefer to call them) are similar.
Cannot be determined if it has 10 as a middle line between the two triangles.

The AA similarity theorem states that if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar. This theorem is based on the Angle-Angle (AA) postulate, which states that if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.
