What does 'Outside' refer to in the context of secants and tangents?

Back

The length of the segment of the secant or tangent that lies outside the circle.

Front

What does 'Whole' refer to in the context of secants?

If a secant and a tangent intersect at a point outside the circle, what is the relationship between their lengths?

Back

The square of the length of the tangent equals the product of the lengths of the secant's outside part and the whole secant.
