Investigate the segments formed by
two intersecting chords, two intersecting secants, an intersecting
tangent and secant and two intersecting tangents as they relate to a
circle with
this menu
driven exploration.
The pages with all options "in view" are shown below.
This program was designed to
be shown on a 1024 x 768 computer
screen.
(This is one file containing 5 different pages.)
|
These pages were designed for classroom
demonstration. Each of the 4 demo pages allows for the
dragging of the endpoints of the segments to create new situations.
The "rule" connected with each situation is hidden under a "Show"
button.

| General (and
simple) Directions: |
|
- Be sure that the students have chosen the arrow in the
upper left hand corner of the screen.
|
 |
- Be sure that the screen is maximized so that the tabs at
the bottom of the screen are visible. (The middle box at
the right is showing a screen in maximized view.)
|
 |
- Read and follow the directions that appear on the page.
"SHOW" means the values will appear when you click on the
button. "HIDE" means the values will disappear
when you click on the button.
|
- To end the exploration, choose FILE - CLOSE. When
the box asking if you wish to "Save Changes" appears, choose
NO. This will keep the file in the same state as
when you started working. None of the students' changes
(or messing) will be saved.
