Line segments, perpendicular lines, and intersecting lines.
Given two lines, each is perpendicular to the other if the angles formed at the vertex are 90 degrees.

They are parts of geometry
Line, line segment, point, skew lines, intersecting lines, perpendicular lines, that's the ones that i can think of off the top of my head
It is a straight line that intersects another straight at 90 degrees.
Line segments, perpendicular lines, and intersecting lines.
Given two lines, each is perpendicular to the other if the angles formed at the vertex are 90 degrees.
If the angle formed between the intersecting lines are 90o then the two lines are perpendicular. In 2D coordinate geometry, a perpendicular line has a slope equal to the negative reciprocal of the original line.

No. Two lines perpendicular to the same line are parallel to each other. I am doing this for my geometry homework right now trying to recall the name of the postulate/theorem stating it.
Perpendicular line segments intersect at right angles. For example, the horizontal and vertical axes on a coordinate plane are perpendicular line segments. In geometry, you can identify perpendicular line segments by measuring the angle they form at their intersection, which should be 90 degrees.
In Euclidean plane geometry, two lines which are perpendicular not only can but must intersect. (I believe the same is true for elliptic geometry and hyperbolic geometry.)

The normal to a surface is an imaginary line that is perpendicular to the surface at a specific point. It indicates the direction that is perpendicular to the surface and is used in geometry and physics to determine angles of incidence and reflection.
