WebJul 21, 2015 · 3 Answers Sorted by: 4 A line is parallel to a plane if the direction vector of the line is orthogonal to the normal vector of the plane. To check whether two vectors are orthogonal, you can find their dot product, because two vectors are orthogonal if and only if their dot product is zero. WebFeb 22, 2011 · Neither: because one line, by itself, can be neither parallel or perpendicular. These characteristics are relevant only in the context of another line (or lines). The given …
WebIn geometry, parallel lines can be defined as two lines in the same plane that are at equal distance from each other and never meet. They can be both horizontal and vertical. We can see parallel lines examples in our daily life … WebFeb 22, 2011 · Normally 2 equidistance lines are needed to designate them as parallel lines. If we say parallel lines, we mean different lines. However, we can say that the line can be parallel to itself if we move it to another dimension. For example, if the line lives in 2D, we can paralleled move it it in the 3D space, and move it again where it was, or ...
WebLet A be the set of all lines in the plane. Let the relation R be defined as: R l2 is parallel to l2. Determine whether S is reflexive, symmetric, or transitive.

It has at least one line joining a set of two vertices with no vertex connecting itself. The concept of graphs in graph theory stands up on some basic terms such as point, line, vertex, edge, degree of vertices, properties of graphs,
WebThe equation of a line parallel to x-axis is of the form y = b and it cuts the y-axis at the point (0, b). This line is parallel to x-axis and is at a perpendicular distance of 'b' units from the x-axis. The slope of the equation of line parallel to x …

For symmetric, if the line l1 is parallel to l2, then l2 is also parallel to l1. Hence it is symmetric. For transitive, if a line l1 is parallel to l2 and line l2 is parallel to l3, line l1 is parallel to l3. It is proved that it is transitive. former alabama players currently in the nflWebSep 10, 1996 · To each line l of Euclidean geometry, associate some other object f ( l ), in such a way that f ( l) = f ( l ') if and only if l and l ' are parallel.
