How to use Right Angles
ENTERING DIMENSIONS:
Entering dimensions in Right Angles is the same as for the FIS Calculator above.
TO START: Before starting the application for the first time you will need to set the default to either
32nds or 16ths in "Settings".
ENTERING TWO SIDES: When
the application starts, the feet, inch and fraction display shows in
the upper left corner of the screen. The rise, base and slope fields of
the triangle are "zeroed" out. This is also how the screen will appear
after pressing the yellow "NEW" button. The "NEW" button will basically
clear everything. At
this point the application is waiting for you to enter a dimension.
After you have entered your dimension, touch the rise, base, or slope
"zero"
dimensions with your finger and the dimension will transfer
from the display to that field, the display will clear, and be ready
for the next dimension to be entered. Enter the next dimension, and
with your finger, touch one of the other "zero" dimensions to enter it
into a field. The remaining information for the right triangle will be
displayed, which includes the third remaining side, the pitch the angle
(decimal), tangent, and area in square feet.
Now enter a new
dimension into the rise, base or slope fields, and the application will
update the other two sides and the area, based on the slope of the
initial triangle that you set up. Sort of like "proportional" triangle
calculations along a given slope. This can continue for as long as you
like with the slope you have set up. When you are ready to set up a new
slope, touch the yellow "NEW" button and the displays will clear, ready
for new input.
ENTERING A SIDE AND AN ANGLE:
As
mentioned above, when the application starts, the feet, inch, and
fraction display is shown. To enter an angle, touch the center of the
screen area to the right of the "feet" display and the "decimal"
display will appear and the "feet" display will disappear. You will
also see the "ANG" field appear and be "zeroed" out as well. The
application is now waiting for an angle to be entered (in decimal form)
into the display. This can be either angle other than the 90 degree
angle which makes it a right triangle. After
entering the angle, touch the blue zeros in the angle field in the
lower right side of the display and the angle will be transfered to
that field, the decimal display will disappear, and the feet display
will appear and be ready to enter a side. Enter your side as explained
above and the application will process the information and display the
remaining info as explained above, and the cycle continues with
"proportional" triangles based on the slope set up.
