What are coplanar lines rays or segments that do not intersect?
If rays, parallel ones. If segments there are many more options because you can have a segment that is not long enough to reach the point of intersection.
A line and a point not on the line are never coplanar?
No, they always are From Wikipedia.org, "The World's Encyclopedia" when I searched coplanar In geometry, a set of points in space is coplanar if the points all lie in the same geometric plane. For example, three distinct points are always coplanar; but four points in space are usually not coplanar. Since 3 points are always coplanar. A point and line are always coplanar
Why cant a system of linear equations cannot have exactly two solutions?
Because linear lines can't intersect in two seperate places. They either intersect at one specific coordinate, or the lines are on top of each other and they intersect at every point.
What term describes two lines that have a point in common?
coplanar
What is the intersection of two coplanar lines?
A point or, if the lines are also collinear, the line(s).
What describes coplanar circles that intersect in exactly one point?
Tangential circles.
What are coplanar circles that intersect in one point called?
Tangential circles.
What different relationships can occur between two coplanar lines?
-- They can be parallel, with no points in common, or -- They can intersect in exactly one point.
When are two coplanar circles concentric?
When the centers of both the circles are at the same point.
What are two coplanar lines called that have no points in common?
Coplanar lines that do not intersect (have no common point) are parallel.Two objects are coplanar if they both lie in the same plane, they must either intersect or be parallel.
Is it that if two different circles intersect then they intersect at one and only one point?
If two circles intersect then they have to intersect at two points.
What is a tangent internally?
Two circles in the same plane are externally tangent if they intersect in exactly one point and their intersection of their interiors is empty.
Is it true that three planes can intersect in only one point?
The intersection of three planes can be a plane (if they are coplanar), a line, or a point.
Where do two lines intersect?
In Euclidean space, they could intersect along their whole lengths (in the lines are identical), at a point if they are coplanar and not parallel, or nowhere if they are parallel or skew.
To cross at exactly one point?
To intersect.
The point at which a line and a circle intersect at exactly one point?
Tangent
What is two plane intersect in exactly one point?
point of intersection.
