Two planes intersect at a line. The line where they intersect pertains to both planes. In the same manner, if infinitely many planes intersect each other at the same line, then that line pertains to the infinitely many planes.
If two line segments are congruent then they have the same length.
Collinear lines are on the same line.
If it is a straight line it must be in the same plane. Otherwise not necessarily.
No, they cannot - unless the two lines are effectively the same line.
no because they are two different people
A duologue is a conversation between two people. In drama, a duologue is a dialogue where both people have about the same amount of lines. It's like a monologue but with two people.When two people say the same line at the same time
nope =D
a one line telephone means 1 person can talk at a time and a 2 line telephone means 2 separate people can talk at the same time in the same house
Any two points have to be on some line.
Any two points lie on the same line, since a line can be drawn through any two points.Three points that lie on the same line are described as being "collinear" points.
well, if a line is considered to conect two points, then two people is the minimum line.
If they have the same length.
Congruency means that two things are the same length. Therefore two line segments if the same length are congruent.
a straight line
colinear
If two lines are parallel, then they will both have the same slope.
