A set without tangents in PG(2,q) is a set of points S such that no line meets S in exactly one point. An exterior set of a conic C is a set of points E such that all secant lines of E are external lines of C. In this paper, we first recall some known examples of sets ...
A common tangent is a line that tangents multiple circles, generally two. Tangents can be divided into two types: internal and external tangents. Internal tangents are line segments that pass through the centre of the two circles whereas it is not the ca
The external part of a secant segment is the part of a secant line that joins the outside point to the nearer intersection point. A B R BR is the external part. Theorem 85: If two tangent segments are drawn to a circle from an external point, then those segments are congruent. (Two...
