## When two planes intersect their intersection is always at exactly one point?

Postulate: If two planes intersect, then their intersection is a line. The point Q lies on line m and line l. Postulate: If two lines intersect, then their intersection is exactly one point.

## Do two planes intersect in exactly one line?

Two planes intersect in exactly one point. Two intersecting lines are always coplanar. There is exactly one line through two points.

**Where can two planes intersect?**

Plane-Plane Intersection

- Two planes always intersect in a line as long as they are not parallel.
- To uniquely specify the line, it is necessary to also find a particular point on it.

### Can two planes intersect in a segment?

They cannot intersect at only one point because planes are infinite.

### Can two planes intersect if so what do two planes intersect at?

Explanation: In 3 dimensional Euclidean space, two planes may intersect as follows: If one plane is identical to the other except translated by some vector not in the plane, then the two planes do not intersect – they are parallel. If the two planes coincide, then they intersect in a plane.

**When two planes intersect two lines are formed?**

If two different planes intersect, then their intersection is a line. If a line and a plane have no points in common, then they are parallel. If two planes do not intersect, then they are parallel. If a plane intersects two parallel planes, then the lines of intersection are parallel.

## Can 2 planes intersect at a plane?

## Can a plane and a point intersect?

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). Since 3 = 3 3=3 3=3 is true, we know that the point we found is a true intersection point with the plane.

**When can two planes intersect?**

### What happens when two planes intersect?

When two planes intersect, they form a line.

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

Answer and Explanation: The intersection of two planes is called a line.

**Can a plane and a line intersect in a point?**

In analytic geometry, the intersection of a line and a plane in three-dimensional space can be the empty set, a point, or a line. Otherwise, the line cuts through the plane at a single point.

## When two or more lines intersect at a point?

When two or more lines intersect, they form different angles at the point of intersection. Lines A B ¯ and C D ¯, for example, meet at Point O. They also form four angles at the point of intersection: ∠ C O A, ∠ C O B, ∠ B O D, and ∠ A O D. Have you also noticed two pairs of vertical angles?

## What does it mean for two planes to intersect each other?

Intersecting planes. If two planes are not parallel, then they will intersect (cross over) each other somewhere. Two planes always intersect at a line, as shown on the right. This is similar to the way two lines intersect at a point.

**Do two distinct intersecting lines determine a plane?**

From plane geometry we know that if two lines are intersecting and not coincident then they intersect each other at a unique point . That means they have only one point in common. By intersecting lines we mean the lines having one common point. We proved that two intersecting lines determine a plane . So intersecting lines are always coplanar lines.

### Can two lines intersect at only one point?

In Euclidean geometry two lines can intersect at only one point. In another Geometry, however, two lines may intersect at two points (think surface of a ball). The intersecting line postulate may be equivalent to the number of degrees in a triangle.
