Not unless the chords are both diameters.

Yes, vertical angles are congruent.
If two angles are vertical then they are congruent.
vertical angles are always congruent...they are two nonadjacent angles formed by intersecting lines. Vertical angles are congruent..or equal in measure
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.
Vertical angel
Whenever two lines intersect, vertical angles refers to the angles opposite each other
yes
Vertical angles are always, by definition, congruent. Note: If the two vertical angles are right angles then they are both congruent and supplementary.
Sometimes
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.

That is an important theorem in geometry: if two lines intersect to form adjacent congruent angles, then the lines are perpendicular. Those congruent angles would be right angles.
