Outcomes

In this lesson you will

discover using transformations that tangents are perpendicular to the radius drawn to the point of tangency
discover that tangent segments drawn from a common external point are congruent

By the end of this section students will be able to:

apply inductive reasoning to make conjectures in geometric situations
investigate and make and prove conjectures associated with angle relationships in circles
write proofs using various axiomatic systems and assess the validity of deductive arguments
investigate and make and prove conjectures associated withtangent properties of circles
apply properties of circles
solve problems involving the equations and characteristics of circles and ellipses
develop and apply formulas for distance and midpoint

To be successful in this lesson, it would be helpful to know the following:
