100
A line that intersects two or more lines.
What is a transversal?
100
Angles that occupy corresponding positions.
What are corresponding angles?
100
This states that if two parallel lines are cut by a transversal then the pairs of corresponding angles are congruent.
What is the corresponding angles postulate?
100
In the coordinate plane, lines can be shown to be parallel by using this concept.
What is slope?
100
The first statement and reason come from this.
What is the given?
200
Lines in a coordinate plane have the same slope, and therefore never intersect.
What is parallel?
200
Angles that lie between two lines on the same side of the transversal.
What are consecutive interior angles?
200
This states that if two parallel lines are cut by a transversal, then the alternate interior angles are congruent.
What is the alternate interior angles theorem.
200
True or false: The lines are parallel. Line L passes through (-6,6) and (2,6). Line M passes through (-2,7) and (3,2).
What is false.
200
Each proof ends with this.
What is the objective (prove)?
300
Lines with this characteristic intersect only only once. The product of their slopes is -1.
What is perpendicular?
300
Two angles that lie between the two lines on opposite sedes of the transversal.
What are alternate interior angles?
300
This states that if two parallel lines are cut by a transversal then the pairs of consecutive interior angles are supplementary
What is the consecutive interior angles theorem
300
True or false: These line are parallel. Line Q passes through (-5,9) and (-1,1). Line R passes through (0,7) and (3,1).
What is true.
300
If two angles have the same measure, then this is true
What is "angles are congruent"?
400
Lines with this characteristic never intersect, but do not lie on the same plane.
What is skew?
400
Two angles that lie outside the lines on opposite sides of the transversal.
What are alternate exterior angles?
400
States that if two lines are cut by a transversal so that alternate interior angles are congruent, then the lines are parallel.
What is the alternate interior angles converse
400
Lines that have the same run and the same rise are this.
What is parallel?
400
Proofs are based on this type of reasoning.
What is deductive?
500
The number of lines that can be parallel to another line and pass through a given point.
What is one.
500
Angles that are adjacent and are supplementary.
What is a linear pair?
500
States if two lines are cut by transversal so that alternate exterior angles are congruent then the lines are parallel.
What is the alternate exterior angles converse?
500
Sometime the coordinate plane is referred to as the Cartesian Plane. It was invented by this man.
Who is Renee Descartes
500
a type of proof written as numbered statements and reasons that show the logical order of an argument.
What is a two column proof.
