Two lines that coincide look and act exactly like a single line. If you have one straight line, there are an infinite number of planes in which it lies.
false
No. The planes must either coincide (they are the same, and intersect everywhere), be parallel (never intersect), or intersect in exactly one line.
yes, if it happened that they all intersected at the same point. otherwise,three lines, assuming they are non-parallel or they do not coincide, would have at most two intersection points (one for each other line)
The graphical solution of two straight lines, if it exists, is a single point. If such a point exists, its mean will be itself.
Same slope and intercepts
Two lines that coincide look and act exactly like a single line. If you have one straight line, there are an infinite number of planes in which it lies.
They have an infinite number of solutions.
In science, "coincide" typically means when two or more events or conditions happen to overlap or occur at the same time or place. It implies a relationship of synchrony or alignment between different factors being studied.
Zero. A null angle is formed by two straight lines that coincide.
Two things that are coinciding are happening at the same time.
They are four lines that coincide pairwise in at least four distinct points.
They have equal slopes, equal y-intercepts, equal x-intercepts,and if they are line segments, then they have equal lengths.
false
No. All of them do but two. The latitude lines at 90 degrees North and South actually coincide with the intersection of all longitudinal lines. So technically, because they coincide, they do not form any angle.
it means that two straight lines that will never connect
No. The planes must either coincide (they are the same, and intersect everywhere), be parallel (never intersect), or intersect in exactly one line.
