Solve what, exactly? Describe the problem. What is the importance of the graph?

I have to make a program and when I run it, it has to make these two shapes.

I am trying to pass a test, and, in one of the questions, the professor asked us to make this.

r_shape = [-1 0; 0 -1; 1 0; 0 1];
t_shape = [-0.5 -0.866; 1 0;  -0.5 0.866];
plot(r_shape([1:end 1], 1), r_shape([1:end 1], 2), 'r-');
hold on
plot(t_shape([1:end 1], 1), t_shape([1:end 1], 2), 'b--');
axis equal
grid on
axis([-1 1 -1 1])
