## What is the line of intersection of two planes?

The intersection of two planes is always a line If two planes intersect each other, the intersection will always be a line.

## Can the intersection of 2 planes be a line?

The intersection of two planes is a line. They cannot intersect at only one point because planes are infinite. Furthermore, they cannot intersect over more than one line because planes are flat.

**What is the intersection of a plane and a line called?**

If a line and a plane intersect one another, the intersection will be a single point, or a line (if the line lies in the plane). Putting these values together, we can say the point of intersection of the line and the plane is the coordinate point.

### What are intersecting planes?

Intersecting planes are planes that intersect along a line. Planes p and q do not intersect along a line. They are parallel.

### When two planes intersect two lines are formed True or false?

12 Cards in this Set

One and only one distinct line can be drawn through two different points. | True |
---|---|

If two different planes intersect, then their intersection is a line. | True |

If a line and a plane have no points in common, then they are parallel. | True |

If two planes do not intersect, then they are parallel. | True |

**When a line and a plane intersect they intersect at a?**

single point

If a line and a plane intersect one another, the intersection will be a single point, or a line (if the line lies in the plane). This will give us the coordinates of the point of intersection.

#### How to plot a plane (dip direction) on a stereonet?

Stereonets: Plotting a Plane (Dip Direction) Example: 68/219° (dip/dip direction) 0° 20° 40° 68° Count off the dip angle and mark it on the tracing paper. Then draw in the great circle for the Rotate the tracing specified plane. paper until the mark you made is lying on the east-west diameter of the stereonet.

#### What is a stereonet projection?

Stereonets involve the projection of lines or planes onto a sphere; two alternative projections are commonly used, the upper and lower hemisphere respectively, with use depending on the discipline of interpretation. See example to the left. Projections are usually completed on pre-formatted nets.

**What are three possibilities for the intersection of two planes?**

The Intersection of Two Planes Similarly, there are also three possibilities for the intersection of two planes- The two planes intersect in a line The normal vectors of the planes are not scalar multiples of each other.

## What is the pole of a stereonet?

The pole is the normal to the plane (i.e. the vector that is perpendicular to the plane). Stereonets: Plotting a Pole The pole (or normal vector) of a plane allows the plane to be represented on the stereonet as a single point.
