• Chapter 4 Congruent Triangles

    Objectives:
    identify and classify triangles by angle measures and side measures
    apply the triangle sum theorem
    apply the exterior angle theorem
    name and use corresponding parts of congruent polygons
    prove triangle congruent using the definition of congruence
    test triangle congruence using SSS SAS AAS ASA
    use properties of isosceles and equliateral triangles
    identify reflections, translations, rotations.
    verify congruence after a congruence transformation
     
     
    Define the (vocabulary) in your notebooks, include examples
