Proving Lines are Parallel
Properties of Parallel Lines
100
A line that cuts through 2 ore more lines at different points.
What is transversal?
100
The symbol for perpendicular.
What is upside down capital T?
100
The symbol for parallel.
What is the diagonal double 
?
100
True or False: Sometimes there is not enough information to prove that lines are parallel.
What is true?
100
If two lines are perpendicular to the same line, one can conclude that:
What is the two lines are parallel?
200
The top and bottom of a box would be defined as _________________ ________________.
What are parallel planes?
200
If two lines are perpendicular to one another, this is the number of right angles that are created.
What is 4?
200
Another word for same-side interior angles.
What is consecutive interior angles?
200
If the lines being cut by a transversal are going to be parallel, and one angle is 40 degrees, the corresponding angle is going to be:
What is 40 degrees?
200
If a line is parallel to a given line, and another line is parallel to that given line, the three lines have to be:
What is parallel?
300
Corresponding Angles are a pair of angles that are in the _________________ __________________.
What is same position?
300
The word used for two angles whose sum is 90 degrees.
What is complementary?
300
If two parallel lines are cut by a transversal, the corresponding angles will always and forever be
What is congruent?
300
True or False : IF vertical angles formed by two lines and a transversal are congruent that means that the lines being cut by a transversal must be parallel.
What is False?
300
When the transversal is perpendicular to two parallel lines, the alternate exterior angles will measure:
What is 90 degrees?
400
If a pair of angles are on opposite sides of a transversal and are contained between two lines, they would be classified as:
What are Alternate Interior Angles?
400
If a linear pair is made of two congruent angles, then each angle is:
What is 90 degrees?
400
The symbol for congruent.
What is the equal signs with a squiggle on top?
400
When looking at same-side interior angles if the two angles add up to equal 180, you can conclude that:
What is the two lines are parallel?
400
When a transversal is perpendicular to a pair of parallel lines, the same-side interior angles will be:
What is supplementary?
500
Perpendicular lines have ______ point(s) of intersection.
What is 1?
500
Same-side exterior angles will always be:
What is supplementary?
500
Fix the error: If two alternate exterior angles are supplementary, then the two lines being cut by the transversal are parallel.
What is congruent?
500
If a transversal cuts through a pair of parallel lines and one of the same-side interior angles is 54, then the other angle must be:
What is 126 degrees?
