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.
To verify the congruence of triangles, you can use several postulates or theorems, such as the Side-Angle-Side (SAS) Postulate, which states that if two sides of one triangle are equal to two sides of another triangle and the included angle is also equal, then the triangles are congruent. Alternatively, the Angle-Side-Angle (ASA) Postulate can be used if two angles and the included side of one triangle are equal to the corresponding parts of another triangle. Other methods include the Side-Side-Side (SSS) Postulate and the Angle-Angle-Side (AAS) Theorem. The specific postulate or theorem applicable depends on the given information about the triangles.
Two sides and the included angle of one triangle must be congruent to two sides and the included angle of the other.
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.
If triangle ABC is congruent to triangle DEF, the postulate that applies is the Side-Angle-Side (SAS) Congruence Postulate. This postulate states that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the triangles are congruent. Other applicable postulates could include Side-Side-Side (SSS) or Angle-Side-Angle (ASA), depending on the specific information given.
To use the SAS (Side-Angle-Side) postulate to prove two triangles congruent, you need to establish that you have two sides of one triangle that are equal in length to two sides of the other triangle, along with the included angle between those two sides being congruent. Specifically, you need the lengths of the two sides for both triangles and the measure of the angle between those sides in at least one of the triangles. If this information is provided, you can apply the SAS postulate effectively.

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.
To determine if triangles UVW and XYZ are congruent, we need information about their corresponding sides and angles. If we know that all three sides of triangle UVW are equal to the three sides of triangle XYZ (SSS postulate), or if two sides and the included angle of one triangle are equal to two sides and the included angle of the other (SAS postulate), then they are congruent. Without specific measurements or relationships, we cannot conclude congruence.
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.
