ALTERNATE DEFINITION:
Angles formed by intersecting
lines that share a vertex, but not
a side. (THIS IS A BETTER
DEFINITION.)
Complementary Angles:
Two angles whose sum of their measures
o
is 90
Supplementary Angles:
Two angles whose sum of their measures
o
is 180
Special facts: (not part of the
definitions)
*Vertical Angles are Congruent
*Angles in a linear pair are
supplementary.
