Perpendicular.
Drawing circles, bisecting angles and creating perpendicular lines just to name a few
Assume that all distances are measured along the appropriate perpendicular. There is no specific name for the locus since the locus can be two or one straight lines, depending upon the original two lines. If the two lines are intersecting then the locus is a pair of straight lines that bisect the two angles formed by the original lines. If the original two lines are parallel, then the locus is a line parallel to them and halfway between them.
They are called perpendicular.
All angles are formed by two intersecting lines. The pairs of angles opposite each other are called vertical angles. If two angles are vertical, they measure the exact same. Say you name the angles formed as A, B, C, and D. A and C are vertical and B and D are vertical. The angles next to each other formed by intersecting lines are supplementary, and add up to 180 degrees. That means A + B = 180 (since they are next to each other) and B+C = 180. Subtracting the first equation by the second equation gives us A + B - B - C = 180 - 180, which simplifies to A - C = 0, which further simplifies to A = C. The same can be said about B and D being equal.

Non-perpendicular intersecting lines. There is no special name.

A normal is at right angles to the tangent. Another name is perpendicular.

Perpendicular lines meet at 90 degrees
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.
