What else can I help you with?
Three lines that intersect in a point but do not all lie in the same plane?
collinear plane
Do three lines intersect in only one point?
It's possible, but for any three lines in the same plane, there could be ether one point of intersection (unlikely) or three (more probably).
Can three lines intersect a on point?
Yes, in Euclidean geometry, an infinite number of lines can meet at one point.
Do 3 lines that intersect in 3 points?
A triangle? Three lines that intersect in three points.
If a transversal intersect two lines then the lines are parallel if and only if a pair of alternate interior angles are equal?
Yes (assuming all three lines are in the same plane).
Three lines that intersect in a point but do not all lie in the same plane?
collinear plane
Three lines that intersect at the same point must all be in the same plane?
no
Does three points intersect at a single point?
No, only three lines can intersect at a single point.
Do three lines intersect in only one point?
It's possible, but for any three lines in the same plane, there could be ether one point of intersection (unlikely) or three (more probably).
Does three lines intersect at the same point must all be in the same plane?
No. Any pair of the three will describe a plane, so the three possible pairs describe three planes.
Three or more lines that intersect at a common point?
its the point of concurrency
What are three or more lines that intersect at a common point called?
concurrent lines
When three or more lines intersect at one point then the lines are said to be?
concurrent
What do you need to make a polygon?
Three or more straight lines in a plane such that they intersect pairwise.
Can three lines intersect a on point?
Yes, in Euclidean geometry, an infinite number of lines can meet at one point.
Can three lines intersect in only one point?
Any number of lines can intersect all at the same point. Think of a circle. Now think of all of its diameters.
Are skew lines parallel?
No. If they are parallel, then a plane exists which both lines lie in. Skew lines can not be on the same plane.
