Today we added a new circle definition to our lexicon.
A secant is a line that intersects a circle at two points.
We then looked at two theorems the Secant-Secant Rule and the Secant-Tangent Rule.
Secant-Secant Rule: (Whole Secant)(External Part) = (Whole Secant)(External Part)
Secant-Tangent Rule: (Whole Secant)(External Part) = Tangent^2
