Congruence of Triangles

Identify the congruent triangles in the following pair of triangles: Triangle ABC and Triangle DEF, where AB = DE, BC = EF, and AC = DF.

• Triangle ABC and Triangle DEF

• Triangle ABE and Triangle DEF, where AB = DE, BE = EF, and AE = DF

• Triangle ABC and Triangle DEF, where AB = DE, BC = EF, and AC = DF

• Triangle ABD and Triangle DEF, where AB = DE, BD = EF, and AD = DF

What criteria is this.

• ASA criteria

• RHS criteria

• SAS criteria

Does the rotating of the figure change the fact that two shapes are congruent?

• Yes

• No

• Maybe

• It makes no sense

What is the meaning of congruent?

• figures having the same angle, shape and size

• figures having same shape and size

• figures having the same shape but not same size or angle

Identify the congruent parts of Triangle RST and Triangle LMN, given that RS = LM, ST = MN, and angle R = angle L.

• RS, LM, ST, MN, angle R, angle L

• RT, LM, angle N

• RS, MN, angle T

• RT, LN, angle S

State the criteria for proving two triangles congruent using AAS congruence.

• Two triangles are congruent using AAS congruence if two angles and the non-included side of one triangle are congruent to two angles and the non-included side of another triangle.

• Two triangles are congruent using AAS congruence if the hypotenuse and one leg of one triangle are congruent to the hypotenuse and one leg of another triangle.

• Two triangles are congruent using AAS congruence if all three sides of one triangle are congruent to all three sides of another triangle.

• Two triangles are congruent using AAS congruence if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle.
