G.CO.B.6, G.CO.B.7, and G.CO.B.8 - Congruence Through Rigid Motions

Triangle ABC is reflected across the y-axis to create triangle A'B'C'.

Two triangles have two pairs of corresponding sides and the included angle congruent.

Quadrilateral ABCD is mapped onto A'B'C'D' by a sequence of rigid motions.

Triangles PQR and P'Q'R' are shown.

For each statement, decide if it is Always True, Sometimes True, or Never True.

Triangle ABC is mapped onto Triangle A'B'C' by a sequence of transformations.

Which sets of information are sufficient to prove that two triangles are congruent through a sequence of rigid motions?

The quadrilateral ABCD is reflected across the y-axis and then translated 4 units left.

Triangles DEF and ABC are shown.
