Section 6.1: Radian Measure

Sketchpad files Here is the Sketchpad file, showing the relationship between arc length and radius, that we made in class: 6-1-S.gsp

Applet This applet shows the relationship between arclength and radius; it was created from the file 6-1-S.gsp (it didn't convert so well).
