Conclusions

- Radii are congruent (not what I was expecting, but important nonetheless)
- Distance from point of tangency to point of intersection for two tangents is equal
- Line connecting center of circle to point of intersection is an angle bisector
- The angle formed between radius and tangent is a right angle
- The angle formed by intersecting chords is equal to half the sum of the intercepted arcs

Students then began work on U9 WS2.
