Lesson 4-1 Congruent figures
Congruent:() When two figures having the same size and shape
Congruent Triangles: IIF (If and only if) two triangles have vertices that can be matched up so that the Corresponding parts (angles and sides) of the triangles are congruent.
Triangle ABC fits exactly over triangle DEF, this makes the two triangles congruent.
The sides and angles will then match up like this:
Corresponding parts of congruent triangles are congruent.
Congruent Polygon: IIF 2 polygons have vertices that can be matched up so that their corresponding parts are congruent.
