Triangles Congruent
Section 4-5
AAS Theorem
• If two angles and a nonincluded side of one triangle
are congruent to the
coresponding parts of
another triangle, then the
triangles are congruent.
AAS Example
HL Theorem
• If the hypotenuse and a leg of one
right triangle are congruent to the
corresponding parts of another
triangle, then the triangles are
congruent.
• Hypotenuse is side opposite right
angle, legs are other two sides.
HL Example
