They come together at the North and South Poles.
They don't. Lines of longitude come together at the North and south Poles.
An illusion. Parallel lines, by their nature can never come together.
It means that they come together and intersect.
Where the slope is steep the contour lines will come close together.
vanishing point
All of the meridians of longitude converge (come together) at the north and south poles.
Perpendicular Lines are two or more lines that will intersect (come together) at some point along their paths. Paralell lines are 2 or more lines that will never intersect at any point in their paths.
No, a ray is a straight line with no ending points. And a polygon has lines that come together at points.
If you mean the longitude lines, as seen on a globe, they meet at the North Pole and at the South Pole.
An allied angle is an angle that is found on an interior line. An interior angle is the angle where to lines come together.
All meridians of longitude converge at the north and south poles.
You could describe lines of longitude as going from side to side, but since the Earth is a sphere (or more precisely, an oblate spheroid) the lines that go from side to side still come together at the poles.
