4.   Use imagination and creativity to design models or games derived from these basic shapes.

Start with the basic shape


if you add a triangle to the right, you get a square square

Starting with the basic shape again,


add a triangle on the top left gives you a parallelogram parallelogram

Again, start with the basic shape


adding another triangle on the bottom left you get an isosceles triangle itriangle

adding  a triangle to the right, you get a trapezoid trapezoid

from the trapezoid, add a triangle on the right for an isosceles trapezoid itrapezoid

or add a triangle on the left for a rectangle rectangle
