If two chords are congruent, what can be said about their distances from the center of the circle?
Congruent chords are equidistant from the center of the circle.
Congruent chords are at different distances from the center of the circle.
Congruent chords are always parallel to each other.
Congruent chords have the same length but different angles.
What is the relationship between congruent chords and their arcs?
Congruent chords in a circle subtend congruent arcs.
Congruent chords are always equal in length.
Congruent arcs are always equal in length.
Congruent chords do not affect the arcs they subtend.
How do you determine if two chords are congruent?
Two chords are congruent if they are the same length.
Two chords are congruent if they are parallel.
Two chords are congruent if they subtend equal angles at the center.
Two chords are congruent if they are equidistant from the center.
If two arcs are congruent, what can be said about the chords that subtend them?
The chords that subtend congruent arcs are also congruent.
The chords that subtend congruent arcs are unequal.
The chords that subtend congruent arcs are perpendicular to each other.
