Download Congruent Triangles

To be or not to be congruent
That is the question?
SSS – Side Side Side
ASA - Angle Side Angle
SAS - Side Angle Side
AAS - Angle Angle Side
Hyp – S - Hypotenuse - Leg


SSS
If three sides of one triangle are congruent to
three sides of a second triangle, the two
triangles are congruent.


ASA
If two angles and the included side of one
triangle are congruent to two angles and the
included side of another triangle, the triangles
are congruent.


SAS
If two sides and the included angle are
congruent to two sides and the included angle
of a second triangle, the two triangles are
congruent.


AAS
If two angles and a non included side of one
triangle are congruent to two angles and the
corresponding non-included side of another
triangle, the two triangles are congruent.


Hyp-S
If the hypotenuse and the leg of one right
triangle are congruent to the corresponding
parts of the second right triangle, the two
triangles are congruent

SSA – Side Side Angle
AAA – Angle Angle Angle


SSA
Two triangles with two sides and a nonincluded angle equal may or may not be
congruent.


AAA
If two angles on one triangle are equal,
respectively, to two angles on another triangle,
then the triangles are similar, but not
necessarily congruent.
