Type: Formative Assessment

Showing Triangles Congruent Using Rigid Motion:

Students are asked to use the definition of congruence in terms of rigid motion to show that two triangles are congruent in the coordinate plane.

Type: Formative Assessment

Proving Congruence Using Corresponding Parts:

Students are asked to prove two triangles congruent given that all pairs of corresponding sides and angles are congruent.

Type: Formative Assessment

Showing Congruence Using Corresponding Parts - 2:

Students are given two triangles in which all pairs of corresponding parts are congruent and are asked to use the definition of congruence in terms of rigid motion to show the triangles are congruent.

Type: Formative Assessment

Showing Congruence Using Corresponding Parts - 1:

Students are given two triangles in which all pairs of corresponding parts are congruent and are asked to use the definition of congruence in terms of rigid motion to show the triangles are congruent.

Type: Formative Assessment

Congruence Implies Congruent Corresponding Parts:

Students are given two congruent triangles and asked to determine the corresponding side lengths and angle measures and to use the definition of congruence in terms of rigid motion to justify their reasoning.
