Have slopes that are the same?
same slopes = parallel lines
How do you calculate parallel and perpendicular lines in a given plane?
Take any two lines and look at their slopes. -- If the slopes are equal, then the lines are parallel. -- If the product of the slopes is -1, then the lines are perpendicular.
What are two lines that have different slopes?
They are not parallel.
What is common about parallel lines?
they have the same slopes
Can 2 parallel lines have different slopes?
No
How are the slopes of parallel lines related?
The slopes of two parallel lines will be the same.
What kinds of slopes do parallel lines have?
The slopes of parallel lines are by definition equal.
Have slopes that are the same?
same slopes = parallel lines
How do you calculate parallel and perpendicular lines in a given plane?
Take any two lines and look at their slopes. -- If the slopes are equal, then the lines are parallel. -- If the product of the slopes is -1, then the lines are perpendicular.
If two lines have slopes that are negative reciprocals of each other then they are if they have slopes that are the same then they are?
negative reciprocal slopes ---> the lines are perpendicular equal slopes ---> the lines are parallel
What is the relationship between the slopes of two parallel lines?
Parallel lines have the same slope.
Are two lines with different slopes are parallel?
No, only lines that have the same slope can be parallel.
Which lines or segments are parallel justify your answer with a theorem or postulate?
Parallel lines are parallel. Proof they have same slopes
What kind of lines are they if both slopes are the same?
Parallel lines
What is the relationship of the slopes of parallel lines?
They are the same.
What are two lines that have different slopes?
They are not parallel.
What is common about parallel lines?
they have the same slopes
