Congruent
triangles are triangles that have vertices that can be matched up
so that the corresponding parts (angles and sides) are the same.
|

Triangle 1 fits
exactly over triangle 2, this makes
the two triangles congruent. |
In
congruent triangles the
corresponding parts (angles and sides) are
congruent.
