Substitution Property
If a=b, then a can be substituted for b in any equation or expression
Contropositive
If not q, then not p
Distributive Property
a(b + c) = ab + ac
Transitive Property
If a=b and b=c, then a=c
inverse
If not p, then not q
point
A location in space that is represented by a dot and has no dimension
converse
If q, then p
supplementary angles
Two angles whose sum is 180 degrees
Coplainer
points that lie on the same plane
slope formula
congruent
Having the same measure
symetric property
if a=b, then b=a
Collinear
points that lie on the same line
detatchment
if a hypothesis a conditional statement is true then the conditions is true
counter
an example used to show a conjecture is false
segment bisector
a segment, ray, line, or plane that intersects a segment at its midpoint
Inductive
finding pattern in a specific case and making conjectures
conjecture
to guess
line segment
part of a line with two endpoints
conditional statement
also known as an If Then Statement(p)
plane
a flat surface that has two dimensions and extends forever
Deductive
use facts definition and accepted properties to form a logical argument
ray
has one endpoint and extends indefinitely in one direction
vertical angles
A pair of opposite congruent angles formed by intersecting lines
opposite rays
share an endpoint and extends in opposite direction forming a line
angle bisector
a ray that divides an angle into two congruent angles
skew lines
Lines that do not intersect and are not co plainer
consecutive
following in order
Line
one dimension, am infinite set of points that extends forever in both directions
linear pair
A pair of adjacent angles whose non common sides are opposite rays.
Transversal Line
a line that intersects two parallel lines
midpoint formula
(x₁+x₂)/2, (y₁+y₂)/2
Subtraction Property
If a=b, then a-c=b-c
polygon
Complementary
two angles that add up to 90 degrees
Non-Rigid Transformation
Transformation like a dilation that does not maintain size and shape.
perimeter
The distance around a figure
Proofs
Negation
The opposite of the original statement (~p)
Addition Property
If a=b, then a+c=b+c
Midpoint
A point that divides a segment into two congruent segments
Reflexive Property
a=a
rigid transformation
A transformation that does not change the size or shape of a figure.
Division Property
if a=b and c≠0, then a/c=b/c
Multiplication Property
If a=b, then ac=bc
parrallel
2 lines that lie on the same plane and never intersect
Integers
...-3, -2, -1, 0, 1, 2, 3... all the whole numbers together with their opposites
Segmant Addition Postulate
If B is between A and C, then AB+BC=AC
angle
A figure formed by two rays with a common endpoint(vertex)
Distance Formula
d = √[( x₂ - x₁)² + (y₂ - y₁)²]
