                                  TRIANGLE                 HEP2.HLP

    The Triangle program will  solve for the unknown sides and  angles of a
    triangle.   The data  is entered  in either  a clockwise  or a  counter
    clockwise direction around the triangle.  You  will be prompted for the
    first side.  This side is followed by an adjacent angle and then by the
    next  side going  around the  triangle.  As  soon as  three values  are
    entered, one of  which must be a  side, the program will  calculate the
    unknown values.  When entering the values  you may just press enter for
    any of  the unknowns.  The  input values  may be numbers,  variables or
    expressions and you  may use the cursor  keys, "Ins" and "Del"  to edit
    your input data. (See help screens to Calculator.)

    In addition to the unknown sides  and angles the program will calculate
    the area of the triangle and  the heights or the perpendicular distance
    from each side to the opposite apex.

    In many  cases you  will want to  chain the  triangle output  values to
    further calculations.  The output values are assigned to variable names
    as shown on the  screen.  You can use these variable  names as input to
    the triangle program, the calculator or any other routine that requires
    numeric input.   To view  the values  stored and  their variable  names
    press  Alt+V.

    It  is possible  to enter  two sides  and one  angle so  there are  two
    triangles that satisfy the input data.    In this case the program will
    give you one solution  and ask if you want the  alternate solution.  If
    it  is not  possible  to compute  a  triangle from  the  input data  an
    appropriate error message will be displayed.
