An isosceles triangle has two equal sides and two equal angles
The SAS Postulate states if two sides and the included angle of a triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.
The postulates that involve congruence are the following :SSS (Side-Side-Side) Congruence Postulate - If three sides of one triangle are congruent to three sides of another triangle, then the triangles are congruent.SAS (Side-Angle-Side) Congruence Postulate - If two sides and the included angle of one triangle are congruent to the corresponding parts of another triangle, the triangles are congruent.ASA (Angle-Side-Angle) Congruence Postulate - If two angles and the included side of one triangle are congruent to the corresponding parts of another triangle, the triangles are congruent.The two other congruence postulates are :AA (Angle-Angle) Similarity Postulate - If two angles of one triangle are congruent to two angles of another triangle, the triangles are similar.Corresponding Angles Postulate - If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent.
The Side Side Side or SSS postulate says f three sides of one triangle are congruent to three sides of another triangle, then the triangles are congruent.
Two sides and the included angle of one triangle must be congruent to two sides and the included angle of the other.
SSS is a postulate used in proving that two triangles are congruent. It is also known as the "Side-Side-Side" Triangle Congruence Postulate. It states that if all 3 sides of a triangle are congruent to another triangles 3 sides, then both triangles are congruent.
Only if the congruent angle is the angle between the two congruent sides (SAS postulate).
The SAS (Side-Angle-Side) postulate.
The SAS Postulate states if two sides and the included angle of a triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.

The postulate that proves triangles PNQ and QRP are congruent is the Side-Angle-Side (SAS) Congruence Postulate. If two sides of one triangle are equal to two sides of another triangle, and the included angle between those sides is also equal, then the triangles are congruent. In this case, if sides PN and QR are equal, sides PQ and RP are equal, and angle PQN is equal to angle QRP, then triangle PNQ is congruent to triangle QRP.
The ASS postulate would be that:if an angle and two sides of one triangle are congruent to the corresponding angle and two sides of a second triangle, then the two triangles are congruent.The SSA postulate would be similar.Neither is true.

To determine if triangle MNO is congruent to triangle PQR, we need to compare their corresponding sides and angles. If they are equal in length and measure, then MNO is congruent to PQR. The specific congruence postulate that could apply is the Side-Angle-Side (SAS) postulate, which states that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, the triangles are congruent.
The Angle Side Angle postulate( ASA) states that if two angles and the included angle of one triangle are congruent to two angles and the included side of another triangle, then these two triangles are congruent.
To prove that two triangles are congruent, you can use the Side-Angle-Side (SAS) Postulate. This states that if two sides of one triangle are equal to two sides of another triangle, and the angle between those sides is also equal, then the triangles are congruent. Alternatively, the Angle-Side-Angle (ASA) Theorem can also be used if two angles and the included side of one triangle are equal to the corresponding parts of another triangle.
You can use a variety of postulates or theorems, among others: SSS (Side-Side-Side) ASA (Angle-Side-Angle - any two corresponding sides* and a corresponding angle) SAS (Side-Angle-Side - the angle MUST be between the two sides, except:) RHS (Right angle-Hypotenuse-Side - this is only ASS which works) * if two corresponding angles are the same, then the third corresponding angle must also be the same (as the angles of a triangle always sum to 180°), and that can be substituted for one angle of ASA to get AAS or SAA.
To prove that triangle SEA is congruent to another triangle, you can use the Side-Angle-Side (SAS) Postulate. This postulate states that if two sides of one triangle are equal to two sides of another triangle, and the angle included between those sides is also equal, then the triangles are congruent. Additionally, if you have information about the angles and sides that meet the criteria of the Angle-Side-Angle (ASA) or Side-Side-Side (SSS) congruence theorems, those could also be applicable.
