Answer:
1, 2 and 4 option - Yes
3 option - No
Step-by-step explanation:
<u>Definition: </u>Vertical angles are the angles opposite each other when two lines cross.
By the definition options
- they are formed by intersecting lines,
- they are opposite to each other
are true.
Vertical Angles Theorem states that vertical angles are congruent. Thus, option
is true.
Option
- they are always supplementary
is false, because supplementary are angles that add up to 180°, but vertical angles can have different measures which do not add up to 180°.

The graphical representation of a system of two linear equations is two lines. These two lines can
(1) interesct at a point (x, y)
(2) not intersect and be parallel (no solution)
(3) sometimes turn out to be the same line (infinitely many solutions).
These are the only possibilities for a system of two linear equations because when graphed, they will only do these three things.
