To divide something into two equal parts.
To divide a line segment into two parts of equal length.
A rectangle’s diagonals are equal and bisect each other, but they are not generally perpendicular. A rhombus’s diagonals are perpendicular and bisect each other, but they are not generally equal.
For a kite, only one diagonal bisects the other. Do not claim that the diagonals bisect each other.
Treat “if and only if” as two implications. Be prepared to prove both perpendicular bisects and bisects perpendicular.
