SOMETIMES. I just did that problem in my California geometry book. They can either be parallel or skew...making the answer sometimes.

Do perpendicular lines always sometimes or never intersect?
Perpendicular lines always intersect and make 90 degree angles. Parallel lines never intersect with each other.
Are intersecting lines always sometimes or never perpendicular?
Sometimes.Perpendicular lines always intersect.Parallel lines never intersect.Therefore, intersecting lines may be perpendicular, but not always.
What is the slope of a line parallel to a line with slope -2?
For two lines to be parallel they must have the same slope. A line parallel to a line with slope -2 would have a slope of -2.
Define parallel and explain how the slope of 2 parallel lines would be related?
I always remembered parallel line because of the 2 "L's" in parallel. They are perfectly parallel to each other and will never intersect. The slope of a line is the rise over run, or rise/run. Therefore if both lines are parallel, the slopes of the lines are the same.
Does parallel lines always have the same slope?
Yes, that's what makes them parallel lines - they have the same slope. So they never will intersect with each other. If a set of lines didn't have the same slope, at some point they would intersect and thus would not be parallel.
How is skew lines are different from parallel lines?
Skew lines are lines that lie on separate planes. and do not intercept parallel lines that are sometimes on the same plane, but don't intersect
What are lines that lie in different planes that do not intersect?
Parallel lines would always lie in the same plane. They would need to be skew lines.
Are parallel lines in space coplanar sometimes?
Parallel lines in Euclidean space are always coplanar.
Can two circles be parallel?
The circles could be in 2 planes that are parallel to each other. Lines and planes can be parallel. Lines of latitude are examples of circles that are in parallel planes.
Are 2 lines in intersecting planes always sometimes or never skew?
sometimes skew
How are parallel lines and parallel planes used in architecture?
parallel lines are used in the white house. The columns holding it up are parallel lines and the floor and the roof of a room are parallel planes as long as they are the same shape
Are parallel lines also called skew lines?
No. Skew lines are lines in different planes that are parallel.
What is the difference between parallel lines and parallel planes?
Parallel lines are two 1-dimensional objects that do not meet. Parallel planes are two 2-dimensional objects that do not meet.
If two parallel planes are cut by a third plane the lines of intersection are?
Parallel lines.
Are a line and a plane that do not intersect always sometimes or never skew?
A line and a plane that do not intersect are always skew. Skew refers to two or more lines or planes that are not parallel and do not intersect. Since a line and a plane are different-dimensional objects, they will never intersect and will always be skew.
Will the perpendicular bisectors of a right triangle always intersect?
yes, because perpendicular lines always intersect. all lines intersect unless they are parallel or on separate planes (skew)
What is the portion of a sphere included between parallel lines?
Parallel lines (as opposed to planes) will not divided a sphere into portions.
