Secant Secant Theorem Calculator: Solve for Circle Segment Lengths

Calculate Secant Secant Theorem Segment Lengths

Enter the total length of the first secant segment.
Enter the length of the external part of the first secant segment.
Enter the total length of the second secant segment.

Unlock the power of circle geometry with our Secant Secant Theorem Calculator. Easily compute unknown segment lengths when two secant lines intersect outside a circle. This tool simplifies complex calculations, making geometry problems a breeze for students and engineers alike.

Formula:

The Secant Secant Theorem states that if two secant segments are drawn to a circle from an exterior point, then the product of the lengths of one secant segment and its external segment is equal to the product of the lengths of the other secant segment and its external segment.

Formula: a × b = c × d
Where:

  • a: Full length of the first secant segment
  • b: Length of the external part of the first secant segment
  • c: Full length of the second secant segment
  • d: Length of the external part of the second secant segment (solved for by this calculator)
