    SAS Triangle Congruence Quiz

    SAS Triangle Congruence Quiz

    by CK-12 //at grade
    Nine question quiz. Students must examine diagrams of triangles and the coordinates of triangles and determine if they are congruent using the SAS congruency theorem. Students must justify their reasoning. Students must also draw (on the coordinate plan) an example and non-example of triangles that can be proven congruent using the SAS theorem and then explain their reasoning.
