APPLY CONGRUENCE AND TRIANGLES
Vocabulary
CONGRUENT
FIGURES
Definition
In two congruent figures, all the parts of one
figure are congruent to the corresponding
parts of the other figure.
In congruent polygons, the corresponding parts
CORRESPONDING are the corresponding sides and the
PARTS
corresponding angles.
*(corresponding- occupies the same position)
THIRD ANGLES
THEOREM
If two angles of one triangle are congruent to
two angles of another triangle, then the third
angles are also congruent.
Reflexive
Property

CONGRUENT
TRIANGLES
For any triangle ABC,
ΔABC ≅ ΔABC.
Symmetric If ΔABC ≅ ΔDEF, then ΔDEF ≅
Property
Transitive
Property
ΔABC.
If ΔABC ≅ ΔDEF and ΔDEF ≅
ΔJKL, then ΔABC ≅ ΔJKL.
