Triangle Congruence: SSS and SAS Principles

The video tutorial covers triangle congruence postulates, specifically SSS (Side-Side-Side) and SAS (Side-Angle-Side). It explains how to determine if two triangles are congruent using these postulates. The tutorial includes a practice game where students identify whether triangles are congruent by SSS, SAS, or if there is not enough information. The video concludes with instructions for students to return to their learning platform for further activities.

What does the SSS postulate state about triangle congruence?

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

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

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

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

Which sides are listed as congruent under the SSS postulate in the example?

• AB to EF, BC to DF, AC to DE

• AB to DE, BC to DF, AC to EF

• AB to EF, BC to DE, AC to DF

• AB to DE, BC to EF, AC to DF

What is required for two triangles to be congruent under the SAS postulate?

• Three angles must be congruent.

• Two sides and the included angle must be congruent.

• Two angles and the included side must be congruent.

• Three sides must be congruent.

In the SAS postulate example, which angle is included between the congruent sides?

• Angle B and Angle E

• Angle A and Angle D

• Angle C and Angle F

• Angle A and Angle C

Which triangles were used to demonstrate the SAS postulate?

• Triangles XYZ and PQR

• Triangles MNO and STU

• Triangles GHI and JKL

• Triangles ABC and DEF

How is triangle congruence determined in the game 'SSS or SAS'?

• By measuring the angles and sides during the game.

• By checking if the triangles have the same color.

• By checking if either the SSS or SAS postulates can be applied.

• By guessing and checking answers randomly.

What does 'not enough information' imply in the context of the game?

• Triangle congruence cannot be determined with the given data.

• Triangles are definitely congruent.

• Triangles are definitely not congruent.

• The game has an error or mistake.

Which postulate was incorrectly assumed to be HL in the game explanation?

• HL postulate

• SSS postulate

• SAS postulate

• ASA postulate

What additional information is needed for the SAS postulate if an angle and one side are given?

• One more angle

• One more side

• Two more sides

• No additional information is needed

What does the teacher encourage students to do at the end of the video?

• Focus only on the game and ignore the postulates.

• Wait for the next video without reviewing.

• Forget everything learned in the video.

• Practice the concepts on the learning platform.
