The Vertical Angles Theorem says that a pair of vertical angles are always congruent.

90 degrees

it depends on the angle. Right angles always have 90 degrees. You can use a protractor to measure the angle

Opposite angles are the angles opposite each other on an x but vertical angles are the angles that are opposite and congruent.

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.

The Vertical Angles Theorem says that a pair of vertical angles are always congruent.

It can be almost any measure but the important thing to remember is that vertical angles are congruent, so any angle that is vertical to another has the same measurement as the angle it is vertical to.

Vertical angles have the same angle measure. Vertical angles are formed by two intersecting lines that look like an "x". Angles that are across from each other on this "x" are called vertical angles.

90 degrees

It is a right angle, or an angle whose measure is 90 degrees or pi/2 radians.

they should be all 180degrees if i understand what you are saying

A reflex angle is one whose measure is greater than 180 degrees but less than 360 degrees. Vertical angles can be reflexive.

Because if they werent, they would eventually form an angle.
