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.

Remember:
The corresponding parts of a triangle are congruent.
