What else can I help you with?
What is the term for lines that don't intersect?
Coplanar lines that don't intersect are parallel. Lines that are not parallel and do not intersect are skew lines.
Do parallel intersect?
no they are straight lines that never intersect, intersecting lines intersect.
Do skew lines always intersect?
Skew lines never intersect. If two lines intersect, then they are known as "intersecting lines", not skew lines.
Do lines that skew intersect?
No. Skew lines do not intersect
Which phrase describes perpendicular lines the lines never touch or the lines intersect at a right angle or the lines intersect at an acute angle or the lines intersect at a obtuse angle?
Lines that intersect at right angles.
Do perpendicular lines intersect in at least two points?
Perpendicular lines intersect at one point only.
What is a counterexample for three coplanar lines always make a triangle?
If at least two of the three lines are parallel, the three lines will not form a triangle.
Counterexample for two lines in a plane always intersect in exactly one point?
Line #1 ==> Y = x Line #2 ==> Y = x + 1 These two lines are parallel, have no points in common, and never intersect. (3 ways to say the same thing)
Do perpendicular lines intersect in and at least to points?
Perpendicular lines are lines that always intersect either at just one point, two points or several more.
What is parallel planes?
Lines in the same plane that do not intersect Lines in the same plane that do not intersect Lines in the same plane that do not intersect Lines in the same plane that do not intersect
What is the term for lines that don't intersect?
Coplanar lines that don't intersect are parallel. Lines that are not parallel and do not intersect are skew lines.
Do parallel intersect?
no they are straight lines that never intersect, intersecting lines intersect.
Do skew lines always intersect?
Skew lines never intersect. If two lines intersect, then they are known as "intersecting lines", not skew lines.
Do lines that skew intersect?
No. Skew lines do not intersect
Which phrase describes perpendicular lines the lines never touch or the lines intersect at a right angle or the lines intersect at an acute angle or the lines intersect at a obtuse angle?
Lines that intersect at right angles.
What are 2 lines that do not and will not intersect?
2 lines that do not and will not intersect are called parallel lines.
Can perpendicular lines intersect in at least two points?
Yes, but only if they are mutually coincident.
