Geometry Terms-Holt

segment addition postulate if q is between p and r, then PQ + QR = PR
reflexive property a=a
symmetric property if a =b, then b=a
transitive property if a=b, then b=c, then a = c
addition property if a = b, then a + c = b + c
subtraction property if a = b, then a - c = b - c
multiplication property if a = b, then ac = bc
Division Property if a = b and c is not equal to 0, then a/c = b/c
substitution Property if a = b, then a may be replaced by b in any equation or expression.
Distributive Property a(b + c) = ab + ac
vertical angles two nonadjacent angles formed by 2 intersecting lines. vertical angles are congruent
linear pair adjacent angles whose noncommon sides are opposite rays. sum = 180 degrees
complementary angles two angles whose measures have a sum of 90 degrees
supplementary angles two angles whose measures have a sum of 180 degrees
right angle an angle whose measure is 90 degrees
acute angle angles smaller than a right angle
obtuse angle angles larger than a right angle
straight angle has a measure of 180 degrees
collinear points on the same line
coplanar points on the same plane
bisector intersects at its midpoint
midpoint a point M is the midpoint of segment PQ if M is between p and Q and PM = MQ
