### Why do parallel lines always make vertical angles?

Wrong statement. Parallel lines don't always make
vertical angles without the transversal, the line that passes
through these lines. Without the transversal, we can't make the
conclusion that parallel lines form vertical angles.

###### Asked in Algebra, Geometry

### If two straight lines intersect and one angle is 30 degree's what are the other three vertical angles?

When two nonvertical straight lines intersect they form two
congruent pair of nonadjacent angles, which are called the vertical
angles (or vertical opposite angles).
So that one of the three vertical angles is 30 degrees, and the
other two angles have a measure of 150 degrees each, since they are
adjacent to a 30 degrees angle.

### What is a z angle?

When two parallel lines are intersected by a transverse line,
they form eight angles. You can consider the parallel lines as the
horizontal lines of the letter Z and the transversal as the sloped
line of Z. Then the two angles in that Z-shape are the Z angles.
The transversal for Z-angles can slope either way.
It can be proved that Z-angles, properly called ALTERNATE
angles, are equal.
