Triangle Congruence: SSS & SAS Concepts

What is the main goal of Section 4.2 in the video?

• To learn about different types of triangles

• To prove two triangles are congruent using specific postulates

• To understand the properties of angles

• To calculate the area of triangles

What does the SSS postulate state?

• If three angles of one triangle are congruent to three angles of another triangle, then the triangles are congruent.

• If two angles and a side of one triangle are congruent to two angles and a side of another triangle, then the triangles are congruent.

• If three sides of one triangle are congruent to three sides of another triangle, then the triangles are congruent.

• If two sides and a non-included angle of one triangle are congruent to two sides and a non-included angle of another triangle, then the triangles are congruent.

What is the significance of the order in which the triangles are written?

• It determines the type of triangle.

• It ensures the corresponding sides and angles are matched correctly.

• It affects the area calculation.

• It changes the congruence postulate used.

What is the key concept to remember about the SAS postulate?

• The included angle must be between the two sides being compared.

• Any angle can be used as long as two sides are congruent.

• The sides do not need to be congruent.

• The angle can be outside the triangle.

Which of the following is NOT a requirement for the SAS postulate?

• The angle must be between the two sides being compared.

• Two sides of one triangle must be congruent to two sides of another triangle.

• The included angle between the two sides must be congruent.

• All three sides of the triangles must be congruent.
