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.
All of the meridians of longitude converge (come together) at the north and south poles.
No, a ray is a straight line with no ending points. And a polygon has lines that come together at points.
An allied angle is an angle that is found on an interior line. An interior angle is the angle where to lines come together.
Contour lines that are closer together indicate a steeper slope. The closer the lines are together, the greater the slope of the terrain.
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.
The lines that run north to south come together at the North and South Poles. The North Pole is located at 90 degrees north latitude, while the South Pole is located at 90 degrees south latitude. These points represent the earth's axis of rotation.
That is typically referred to as the climax of the story, where all the separate plot-lines come together and reach their highest point of tension or conflict.
