Are two lines that do not intersect skew?
Two lines that are not parallel and do not intersect are skew. If the non-intersecting lines are in the same plane then they are parallel.
If two angles are not vertical then they are not nonadjacent angles formed by two intersecting lines?
False. The angles can be formed by two skew lines intersecting a third line.
How many planes are determined by two intersecting lines?
One.
Can two intersecting lines lie in two planes?
If they are straight lines, then they define a plane in which both lines lie.
Is it possible for two skew lines to be perpendicular?
perpendicular lines are lines that MEET at right angles (90 degrees). Skew lines are lines that dont meet at all. Even though the gradients of two skew lines can multiply to be -1 (a property of perpendicular lines) They will not really be perpendicular as they don't accually meet. This can occur when the lines are in different planes.
When are two lines in intersecting planes skew?
Each line can either intersect the edge which is common to the two planes at some point or be parallel to it. If the two lines intersect the edge, but at different points, then the lines are skew. If only one of the lines intersects the edge, then again the lines are skew. If neither of them intersect, then the two lines are parallel to the same edge and so they are parallel to one another so not skew.
Do skew lines always intersect?
Skew lines never intersect. If two lines intersect, then they are known as "intersecting lines", not skew lines.
Are two lines that do not intersect skew?
Two lines that are not parallel and do not intersect are skew. If the non-intersecting lines are in the same plane then they are parallel.
If two angles are not vertical then they are not nonadjacent angles formed by two intersecting lines?
False. The angles can be formed by two skew lines intersecting a third line.
Do skew lines intersect if they are in the same plane?
No, skew lines cannot be in the same plane, since they do not have a point on common. Two lines intersect if they lie in a common plane, and by definition, these intersecting lines are not skew lines.
What are two planes that intersect in a straight lines known as?
Intersecting planes!
What is the name of two lines in different planes that do not intersect and are not parallel?
skew lines
Are any two noncoplanar lines skew?
I guess they are. If they're parallel or intersecting, then they're coplanar.
Two lines that do not intersect and are in different planes?
They are skew lines. Two parallel lines must be in the same plane.
Two lines in different planes that do not intersect and are not parallel are called?
skew
How many planes are determined by two intersecting lines?
One.
If two lines are not coplanar then they are neither intersecting nor parallel?
CorrectParallel lines as well as intersecting lines must be coplanar (in Euclidean geometry not quite sure about hyperbolic geometry...).Lines in space which neither are coplanar nor intersecting are called "skew"
