Term
angle addition postulate
Definition
if a point S lies in the interior of ∠PQR, then ∠PQS + ∠SQR = ∠PQR.
Term
law of syllogism
Definition
two conditional statements and forms a conclusion by combining the hypothesis of one statement with the conclusion of another
Term
protractor postulate
Definition
the uniqueness of a ray forming a given angle with a given ray
Term
transitive property of congruence
Definition
If a = b and b = c, then a = c
Term
vertical angle theorem
Definition
When two straight lines intersect at a point, four angles are made. The non-adjacent angles are called vertical
Term
corresponding angle theorem
Definition
When a transversal intersects two parallel lines, the corresponding angles are equal
Term
congruent angle theorem
Definition
If two parallel lines are cut by transversal, then the pairs of corresponding angles are congruent
Term
alternate exterior angle theorem
Definition
when two parallel lines are cut by a transversal, the resulting alternate exterior angles are congruent
Term
alternate interior angles theorem
Definition
when two parallel lines are cut by a transversal, the resulting alternate interior angles are congruent.
Term
same side interior angles theorem
Definition
if a transversal intersects two parallel lines, then same-side interior angles are supplementary
Term
symmetric property
Definition
if a=b then b=a
Term
reflexive property
Definition
a=a
Term
supplementary angles theorem
Definition
two angles that up to 180 degrees
Term
complementary angles
Definition
two angles that add up to 90 degrees
Term
law of detachment
Definition
if p=>q is true and p is true, then q must be true
