When moving around with some of the smaller shapes cut out from the equilateral triangle, we actually got many solutions for making trapeziums using the technique trails and errors but also remembering to include irregular trapeziums. In total, we made 22 trapeziums! To start off, you should write down all the angles in the small shapes, since it's easier to calculate the angles if you actually made a trapezium. Look in the equilateral triangle diagram and see if you can spot any possible trapeziums from just seeing it. After that, try adding more triangles to it to make new ones but be sure to check if the total of the interior angles adds up to 360 degrees.
