Unit 2 Lesson 1 Whiteboards

Front

What does the notation \(\Delta XYZ \cong \Delta TRS\) indicate?

Back

It indicates that triangle XYZ is congruent to triangle TRS, meaning they have the same shape and size.

Front

Which side corresponds to side YZ in the congruent triangles \(\Delta XYZ \cong \Delta TRS\)?

Back

Side RS corresponds to side YZ.

Front

What are corresponding parts in the context of congruent triangles?

Back

Corresponding parts are sides or angles that are in the same or matching position in congruent triangles.

Front

What angle corresponds to Angle D in the congruent triangles \(\Delta XYZ \cong \Delta TRS\)?

Back

Angle R corresponds to Angle D.

Front

What angle corresponds to Angle E in the congruent triangles \(\Delta XYZ \cong \Delta TRS\)?

Back

Angle S corresponds to Angle E.

Front

Which side corresponds to side XY in the congruent triangles \(\Delta XYZ \cong \Delta TRS\)?

Back

Side TR corresponds to side XY.

Front

What is the definition of congruence in geometry?

Back

Congruence in geometry means that two figures have the same shape and size.

Front

How can you determine if two triangles are congruent?

Back

Two triangles can be determined to be congruent using criteria such as SSS (Side-Side-Side), SAS (Side-Angle-Side), ASA (Angle-Side-Angle), AAS (Angle-Angle-Side), or HL (Hypotenuse-Leg for right triangles).

Front

What is the significance of corresponding angles in congruent triangles?

Back

Corresponding angles in congruent triangles are equal, which helps in proving the triangles are congruent.

Front

What is the significance of corresponding sides in congruent triangles?

Back

Corresponding sides in congruent triangles are equal in length, which is essential for establishing congruence.
