Useful functions

area_2d

 #returns area of triangle with vertices (x1, y1) (x2, y2) and (x3, y3)
 area = area_2d(x1, y1, x2, y2, x3, y3)

area_3d

#returns area of triangle in 3d space with vertices (x1, y1, z1) (x2, y2, z2) and (x3, y3, z3)
area = area_3d(x1, y1, z1, x2, y2, z2, x3, y3, z3)

fop

# returns the x, y, z coordinates of the foot of perpendicular drawn from the point (x3, y3, z3) to the line joining (x1, y1, z1) and  (x2, y2, z2) 
xn, xd, yn, yd, zn, zd = fop(x1, y1, z1, x2, y2, z2, x3, y3, z3)
#returns numerator and denominator of the coordinates

gcd

# returns the HCF(highest common factor) or GCD( Greatest common divisor) {both meaning the same} of two numbers
hcf = gcd(a, b)

intersect

# returns the x, y, z, x(as fraction), y(as fraction), z(as fraction) coordinates of the point of intersection of two lines, 
# line 1: x-x1/(a1n/a1d) = y-y1/(b1n/b1d) = z-z1/(c1n/c1d)
# line 2: x-x2/(a2n/a2d) = y-y/2(b2n/b2d) = z-z2/(c2n/c2d)
xn, xd, yn, yd, zn, zd = intersect(x1, y1, z1, x2, y2, z2, x3, y3, z3)

iscollinear

# returns whether the three points in 2d space are collinear or not
value = iscollinear(x1, y1, x2, y2, x3, y3)
# returns True if collinear and False if not

iscollinear_3d

# returns whether the three points in 3d space are collinear or not
value = iscollinear_3d(x1, y1, z1, x2, y2, z2, x3, y3, z3)
# returns True if collinear and False if not

perimeter_2d

 #returns perimeter of triangle with vertices (x1, y1) (x2, y2) and (x3, y3)
 peri = peri_2d(x1, y1, x2, y2, x3, y3)

perimeter_3d

#yreturns perimeter of triangle in 3d space with vertices (x1, y1, z1) (x2, y2, z2) and (x3, y3, z3)
peri = perimeter_3d(x1, y1, z1, x2, y2, z2, x3, y3, z3)
