If you have two (45∘−45∘−90∘) set squares. Which of the following shapes is impossible to produce using them?
All squares are rhombus and parallelograms, hence from the figure given below it can be inferred that a rhombus, a square and a parallelogram can be obtained. We can also make a pentagon as shown in the figure. But we can never get a rectangle using 2 set squares with angles (45∘−45∘−90∘).
