the graphics box is appears you will see a graph containing
100 points and labels for the x and y-axis. This tutorial
will demonstrate how Kinemage can be used to measure distances
and angles on a graph.
Try clicking any point. Notice that the lower left shows the
(x,y) coordinate for the point. The lower right side of the
screen gives the distance between the last two consecutive
points clicked (be sure you are exactly on the point when
you do this). Try clicking several points to demonstrate this
principle. Notice that clicking the same point twice will
leave the same coordinates but change the distance value to

that contains just the text, or you might want to make a hardcopy
by printing the text page. The text for tutorial 2 is available
measure the angle using Kinemage, go to the Other pulldown,
click on Measure. Now click point A, then point B and last
point C. The lower right will give the angle.
is the measure of <ABC using Kinemage? ______.
Is the value in close agreement with your approximation?_______.
distance shown at the lower right will be the distance between
the last two points clicked. Do not be concerned about the
"dhr" value, we will demonstrate this in Tutorial
III. To turn off the measure option, go back to the Other
pulldown and simply click off Measure --the white lines

What is your estimate of the rectangle? ______
the perimeter by measuring the distance of each of the line
segments in the rectangle using Kinemage. What is your answer?________
your knowledge of rectangles, what should each of the angles
of a rectangle be equal to?________
Kinemage what values do you get for each angle?____. The
sum of the angles of a rectangle is ________.

is possible with Kinemage to draw your own images. First
clear the screen of all images, leaving only the points
on the screen. Go to the Other pulldown and click on drawline.
When the drawline box appears click "ON". NOTE:
Make sure the measure command is clicked off or measure
lines will also appear. Click two consecutive points and
a line will appear. You can continue to draw line segments
between any two points. If you wish to erase the last line
you drew, simply click eraseline at the right side of the
screen. If you have drawn several lines, clicking eraseline
will keep erasing lines in order from the last one drawn.
If you wish to erase all lines quickly, return to the drawbox
command under the Other pulldown menu and click off. This
will remove all lines you have drawn.
