If you have two 30∘- 60∘ - 90∘ set squares, which of the following shapes is impossible to get using them?
Rhombus
You know that a rectangle is a parallelogram. In the figures below, we can see that we can make rectangles and also a parallelograms. Also we can make a pentagon. But making a rhombus is impossible by using 2 set squares having 30∘- 60∘ - 90∘ angles.
