**Tangent investigation**First, notice all the parts of this template:

- Secant lines
- Radii as perpendicular bisectors of chords
- Distance measurement points E and I to point I (point of intersection)

- What is the angle between the tangent line and the radius that goes to the point of tangency?
- What is special about the two segments from point of tangency to the point of intersection (point I)?
