Name a chord congruent to chord ZT.
If radius of a circle intersects a chord then it bisects the chord only if radius is perpendicular to the chord.
The radius of the circle that is perpendicular to a chord intersects the chord at its midpoint, so it is said to bisect the chord.
because the chord can be determine by the diameter and the diameter can be determine by the chord.
The mathematical symbol for "no change" is typically represented by the equal sign (=). This symbol indicates that both sides of the equation are equal and there is no change in value. In some contexts, the symbol for no change can also be represented by a horizontal line with an arrow pointing to the right, indicating that the value remains constant over time.
