yes they are because they meet to form at a right angle
Yes they would be congruent and (sometimes) supplementary to each other.
when it is exactly phase
yes
If two angles are vertical then they are congruent.
Vertical angles are always, by definition, congruent. Note: If the two vertical angles are right angles then they are both congruent and supplementary.
vertical angles are always congruent...they are two nonadjacent angles formed by intersecting lines. Vertical angles are congruent..or equal in measure
yes
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.
not all congruent angles are vertical angles. Vertical angles must share a vertex.
Yes, vertical angles are congruent.
Whenever two lines intersect, vertical angles refers to the angles opposite each other
Do you mean the two angles that are formed by two intersecting lines? If yes, they are called vertical angles and they are congruent.
