Copy of Diameters & Chords I (VB)
Once you slide the slider in the applet below, you'll immediately notice a chord drawn and a diameter drawn to this chord.
Interact with this applet for a few minutes, then answer the questions that follow. As always, be sure to change the locations of the BIG POINTS at any time before re-sliding the slider.
Questions:
Notice how this diameter intersects this chord at a right angle. That is, this diameter was drawn so that it's perpendicular to the chord.
If a diameter intersects a chord at a right angle, what does this diameter do to this chord? How was this evidenced in the applet above?
If a diameter intersects a chord at a right angle, what does this diameter do to the entire arc this chord intercepts? How was this evidenced in the applet above?
