2.1- 2.6 

Locus- the set of all possible points that satisfy a set of conditions

Venn diagram- a concept map of overlapping circles or ovals that show the relationship among members of different sets

inductive reasoning- the process of observing data, recognizing patterns, and making generalizations about those patterns

conjecture- a generalization made through inductive reasoning

function rule- a rule that gives the nth term in a sequence

function notation- an equation that expresses the rule

linear functions- rules that generate a sequence with a constant difference; the sequence will form a straight line when graphed

Transformation Vector- The magnitude and distance given for a translation

Deducting reasoning- the process of showing that certain statements follow logically from agreed upon assumption and proven facts

composition- when you apply one transformation to a figure and then another transformation to the image

Converse- switches the order of the if-then statement

transversal- a line intersecting two or more other lines in a plane

corresponding angles- angles that have the same position on the parallel lines with respect to the transversal

Alternate exterior angle- angles that are on the outside of the parallel lines and on opposite side of the transversal

alternate interior angles- angles that are on the interior of the parallel lines on opposite sides of the transversal

same side interior- angles that are on the inside of the parallel line and on the same side of the transversal

Linear pair conjecture- if two angles form a linear pair, then the measures of the angles add up to 180 degrees

vertical angles conjecture- if two angles are vertical angles, then they are congruent

corresponding angles conjecture- if two parallel lines are cut by a transversal, then corresponding angles are congruent

Alternate interior angles conjecture- if two parallel lines are cut by a transversal, then alternate interior angles are congruent

Alternate exterior angles- if two parallel lines are cut by a transversal, than alternate exterior angles are congruent

parallel lines conjecture- if two parallel lines are cut by a transversal, than corresponding angles are congruent, alternate interior angles are congruent, and alternate exterior angles are congruent

Converse of the parallel lines conjecture- if two lines are cut by a transversal to form pairs of congruent corresponding angles, congruent alternate interior angles, or congruent alternate exterior angles, than the lines are parallel.
