1. Perpendicular bisectors

Key Concepts & Definitions

  • Perpendicular bisector: A line or segment that divides a side of a triangle into two equal parts at a 90° angle. It passes through the midpoint of the side and is perpendicular to it.

  • Circumcenter: The point where the three perpendicular bisectors of a triangle intersect. It is equidistant from all three vertices of the triangle.

  • Midpoint: The point that divides a segment into two equal parts. It is the center of the segment.

  • Perpendicular line: A line that intersects another at a 90° angle.

  • Concurrent lines: Three or more lines that intersect at a single point; in this context, the perpendicular bisectors are concurrent at the circumcenter.

Essential Points

  • The perpendicular bisectors of the sides of a triangle are always concurrent; their intersection point is called the circumcenter.

  • The circumcenter can lie inside, on, or outside the triangle depending on the triangle type:

    • Inside for acute triangles
    • On the hypotenuse for right triangles
    • Outside for obtuse triangles
