y = 5
what P.O.E was used?
Subtraction P.O.E
y-2 = 7
y = 9
what P.O.E was used?
Addition P.O.E
y/2 = 4
y = 8
what P.O.E was used?

y = 4
What P.O.E was used?
Division P.O.E
a=a (P.O.E)
Reflexive P.O.E
if a=b, then b=a (P.O.E)
Symetric P.O.E
if a=b, and b=c, then a=c (P.O.E)
Transitive P.O.E
Whats the saying to remember the other P.O.E;s?
RST, 1,2,3
if a=b, then b can be used in place of a
Substitution P.O.E
A pair of angles with a common end point and ray, but no common interior points
Adjacent Angles
A pair of adjacent angles whose non common rays (the shared endpoint) are opposite rays and form a line
Linear Pair
two non-adjacent angles formed by a pair of intersecting lines
Verticle Angles
Two angles who’s measure adds up to 90 degrees
Complementary Angles
