Is it possible to do a cos1 in Turing. I need it for a program that I am creating for finding the degrees of angle and telling if its a right angle triangle or not. I am simply going to use the elseif and else commands. So can you guys help me with the cosine.

arccosd or arccos, depending on whether you want it in radian or degree form.

code:  var a, b, c : real
var x1, x2, x3, y1, y2, y3, t1, t2, t3 : real
var u1, u2, u3, i1, i2, i3 : real
put "Enter the length of side 'a' of the triangle."
get a
put "Enter the length of side 'b' of the triangle."
get b
put "Enter the length of side 'c' of the triangle."
get c
x1 := 2 * (b) * (c)
x2 := 2 * (a) * (c)
x3 := 2 * (a) * (b)
y1 := b ** 2 + c ** 2
y2 := a ** 2 + c ** 2
y3 := a ** 2 + b ** 2
t1 := a ** 2  y1
t2 := b ** 2  y2
t3 := c ** 2  y3
u1 := t1 / x1
u2 := t2 / x2
u3 := t3 / x3
i1 := arccosd (u1)
i2 := arccosd (u2)
i3 := arccosd (u3)
put skip
const z7:= 90
if i1 = z7 then
put "This is a right angle triangle."
end if
if i2 = z7 then
put "This is a right angle triangle."
end if
if i3 = z7 then
put "This is a right angle triangle."
end if
put "Angle A is: ", i1
put "Angle B is: ", i2
put "Angle C is: ", i3

I am having problems exiting this program. I want the program to exit when one of the angle is 90 degrees.
Put these values in as they make a right angle triangle when it asks you when it runs: 1, 2, 1.732050808.
