Perpendicular means 'at right angles to'.
In a triangular based pyramid, the three faces that form the base are perpendicular to the apex of the pyramid, which means they have pairs of perpendicular sides. The other three faces, which are triangular, do not have pairs of perpendicular sides.
VERTICAL LINES-lines that are at right angle and or perpendicular to a plane.HORIZONTAL LINES-lines that are parallel to the horizon.ANGULAR LINES-lines that have sharp edges. They can be long or short.CURVE LINES-lines that are without angles.SLANTING OR DIAGONAL-lines that suggest action or movement.JAGGED LINES-lines that are harsh and unpleasant.
Hi The different types of Alphabet of lines are:-Visible.-cutting plane lines.-Short breaking lines.-Border lines.-Invisible lines .-Ditto or hidden lines.-Center lines.-Long break lines.-Section lines.-Dimension lines

They can, yes.
Generally not, though they can be.
at right angles to
Perpendicular means 'at right angles to'.
yes and then it will be called a right-angled triangle
well... I would say: > a door >A chair >a table leg

Different types of lines are :parallel lines, intersecting lines, perpendicular lines,oblique lines, vertical lines, horizontal lines, zigzag lines, curved lines ,wavy lines, and dashed or dotted lines.
The lines that intercept latitude lines are lines of longitude.

Either parallel lines or longitudinal lines are opposite transversal lines.
