# Do a line and a plane always intersect at a point? ### Do a line and a plane always intersect at a point?

then the line is contained in the plane, that is, the line intersects the plane at each point of the line. Otherwise, the line and plane have no intersection.

### Can a plane and a line intersect?

A given line and a given plane may or may not intersect. If the line does intersect with the plane, it's possible that the line is completely contained in the plane as well. ... If they do intersect, determine whether the line is contained in the plane or intersects it in a single point. BE

### How do you name an intersection of a plane and a line?

### How do you find the point of intersection between a line and a plane?

c) Find all points of intersection of P with the line x = t, y =4+2t, z = t. Answer: a) To find the intersection we substitute the formulas for x, y and z into the equation for P and solve for t. The line is contained in the plane, i.e., all points of the line are in its intersection with the plane.

### How do you find where a line intersects?

How Do I Find the Point of Intersection of Two Lines?

1. Get the two equations for the lines into slope-intercept form. ...
2. Set the two equations for y equal to each other.
3. Solve for x. ...
4. Use this x-coordinate and substitute it into either of the original equations for the lines and solve for y.

### How do you name an intersection on a plane?

2:203:01Given a line, name the two planes that intersect at the line - YouTubeYouTube

### What happens when two lines intersect a plane?

• If you pick two points on a plane and connect them with a straight line then every point on the line will be on the plane. Given two points there is only one line passing those points. Thus if two points of a line intersect a plane then all points of the line are on the plane.

### How are three noncollinear points define a plane?

• "If two lines intersect, then exactly one plane contains the lines." Now, each line contains two points, and according to another theorem in my book: "If two lines intersect, then they intersect in exactly one point." and three noncollinear points define a plane.

### Why are all the points on a plane on the line?

• If you pick two points on a plane and connect them with a straight line then every point on the line will be on the plane. Given two points there is only one line passing those points. Thus if two points of a line intersect a plane then all points of the line are on the plane. share|cite|improve this answer.

### Can a line not intersect with another line?

• If one is not restricted to a plane, then two lines could be non-parallel and yet not intersect. For instance, in 3-dimensional space, one line could be the z -axis (that is, all the points with x = 0 and y = 0 ), and the other line could be the y-axis shifted 1 unit in the x-direction (that is, all the points with x = 1 and z = 0 ).
