SOLUTION: Create a graph with four odd vertices Can you show me please???

Start with a rectangle. A rectangle has 4 EVEN vertices,



one at each of the 4 corners for there are two lines coming 
together at each of the 4 corners, and 2 is an EVEN number.
Now if we add a curved line at the top and another at the 
bottom as shown below, there will be three lines 
coming together at each corner. And since 3 is ODD, these
4 corners of the rectangle are now 4 ODD vertices:
