- modify drawConcentricTriangles() to meet the conditions below

# - accept 4 parameters; a turtle object and 3 integers

# --- you may assume the ints are in increasing size (a < b < c)

# - add a docstring

# - make the turtle object draw 3 concentric triangles around the origin

# - draw triangle 1 in black (side = a)

# - draw triangle 2 in blue (side = b)

# - draw triangle 3 in red (side = c)

# - return the sum of the 3 integer parameters
