Understanding Perpendicular Bisectors in Geometry

Feb 20, 2025

Perpendicular Bisector

Definition

  • A perpendicular bisector is a line that divides a line segment into two equal parts.
  • It intersects the line segment at a 90-degree angle.

Key Points

  • Representation: The perpendicular bisector is shown by a green line in the illustration.
  • Labeling:
    • One side is labeled as A.
    • The other side is labeled as B.
    • The intersecting point of the bisector is labeled as C.

Geometry

  • The angles formed at the intersection are:
    • Angle OCA = 90 degrees
    • Angle OCB = 90 degrees
  • This means that:
    • AC = one equal part of the segment
    • CB = the other equal part of the segment

Conclusion

  • The perpendicular bisector is crucial in geometry for creating equal segments and maintaining right angles.
