Question

If you have two (${45}^{\circ }$-${45}^{\circ }$-${90}^{\circ }$) set squares. Which of the following shapes is impossible to produce using them?

• A. Square
• B. Parallelogram
• C. Pentagon
• D. Rectangle

Answer 1

The correct option is D

Rectangle

We know that all squares are rhombuses and parallelograms. We can also make a pentagon as shown in the figure. But we can never get a rectangle using $2$ set squares with angles (${45}^{\circ }$-${45}^{\circ }$-${90}^{\circ }$).
