because 360 degrees is the total amount of degrees you can get. the degrees are essentially the angle measurement. anything that is 180 degrees is a vertical. so vertical angels are used to indicated a 180degree line.

If two angles are vertical then they are congruent.

Vertical angles can be supplementary angles if the lines are perpendicular and then both of the vertical angles would be 90 digress.

No, because by definition, vertical angles are not adjacent angles. Hope this helps

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

Vertical angles are equal in measure and are formed when two lines intersect. Complementary angles, on the other hand, add up to a total of 90 degrees. They are not directly related, but if two lines intersect and form vertical angles, then the angles adjacent to the vertical angles will be complementary.

Vertical angles are used in construction, computer design, and just about any other field where objects are built. Angles add design and strength.

not all congruent angles are vertical angles. Vertical angles must share a vertex.

Vertical angles are always, by definition, congruent. Note: If the two vertical angles are right angles then they are both congruent and supplementary.

If two angles are vertical then they are congruent.

Vertical angles can be supplementary angles if the lines are perpendicular and then both of the vertical angles would be 90 digress.

No they are not because adjacent angles are on the same side while vertical angles are on the opposite therefore vertical angles are non adjacent.

Vertical angles must necessarily be congruent, however congruent angles do not necessarily have to be vertical angles. An example of congruent angles which are not vertical angles are the 3 interior angles of an equilateral triangle. These angles do not share the same vertex yet they are congruent.

the vertical angles are the same angles as well as horizontal angles but vertical and horizontal are most the time different except when they all are 90 degrees.

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.
