To 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. **What
is the measure of <ABC using Kinemage? ______. Is the value in close agreement
with your approximation?_______.
The 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 that were traced
over the angle will be removed.
Remove the green angle from the screen by clicking off the X from the box named
angle, at the right side of the screen. Click on rectangle. **Estimate
the perimeter of the rectangle by counting squares. What is your estimate
of the rectangle? ______ **Measure
the perimeter by measuring the distance of each of the line segments in the rectangle
using Kinemage. What is your answer?________ **From
your knowledge of rectangles, what should each of the angles of a rectangle be
equal to?________ **Using
Kinemage what values do you get for each angle?____. The sum of the angles
of a rectangle is ________.
Clear the screen of the rectangle. Call up the triangle. **What
is your estimates for: <A=______ <B=_______ <C=________ **What
is your estimate for the perimeter of triangle ABC?______ **Using Kinemage
find <A=______ <B=________ <C=_______ **The perimeter of triangle ABC
using Kinemage is: ___________
Some computers have built in calculators which may help when doing computations
with decimals. Ask your teacher if your computer has a built in calculator.
It 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. Activities
for Students: 1)
Draw your initials using line segments. Measure the distances and angles used
to form the letters. 2)
Try finding the interior angles of each of the polygons shown. What is the sum
of the interior angles of each of the polygons shown? 3)If
you are familiar with the Pythagorean theorem a^2+b^2=c^2 find the diagonal of
the square and rectangle. Check your answer by measuring the diagonal using Kinemage.
3) Try drawing
several angles and polygons and measure their sides and angles. _________________________________________________________________________________________ |
