Yes, the opposite rays of vertical angles are always coplanar, so the angles are as well.

What is the difference between vertical angles and congruent angles?
not all congruent angles are vertical angles. Vertical angles must share a vertex.
Two lines which intersect to form right angles?
...must be coplanar.
What is the difference between a linear pair and vertical angles?
In a Linear Pair the 2 angles add up to 180 degrees while Vertical Angles are just 2 vertical angles that are congruent.
When two coplanar lines are cut by transversal the angles between the two lines on opposite sides of the transversal are called what?
Alternate Interior Angles
Can vertical angles be complementary?
Vertical angles must be congruent so if they are complementary, they must be 45 degrees to be complementary.
How many pairs of vertical angles are formed by 3 coplanar lines intersecting at one point?
Eight.
How many pairs of vertical angles are formed by 5 coplanar lines intersecting at one point?
20....or maybe 18
Are vertical angles formed by two intersecting lines coplanar?
Yes. They're in the plane defined by the two intersecting lines.
What angles do not intersect and are coplanar?
Angles that are separated by a distance. For example, any two angles of any polygon do not intersect and they are coplanar.
Can three coplanar angles have a common side?
NO
What is the difference between vertical angles and congruent angles?
not all congruent angles are vertical angles. Vertical angles must share a vertex.
How many angles can be made by 3 coplanar points?
3
Two coplanar angles with a common side?
adjacent planes
Two 60 degree angles?
make 120° when they are coplanar.
How determine whether the conjecture is true or false. If false give a counterexample. Given LMN and XMZ are coplanar. Conjecture The angles are vertical angles.?
Select one: a. False; the angles may be supplementary. b. True c. False; one angle may be in the interior of the other. d. False; the angles may be adjacent.
Are vertical angles congruent or supplementary angles?
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 what are they?
If two angles are vertical then they are congruent.
