Question

A rhombus can be converted into a square shape without change in length of any of its sides.
Which of following conversion can take place without change in length of sides of both shapes.

• A. Isosceles trapezoid from trapezoid
• B. Parallelogram from trapezoid
• C. Rectangle from Parallelogram
• D. Rectangle from square

Answer 1

The correct option is C Rectangle from Parallelogram

A square can be formed by hinging all the 4 vertices, fixing any side and sliding the opposite side of the fixed side such that all the interior angles become ${90}^o.$


Similarly, a rectangle can be converted from a parallelogram by hinging all the 4 vertices of the parallelogram, fixing any side and sliding the opposite side of the fixed side such that all the interior angles become ${90}^o.$

Hence, the correct option is Rectangle from Parallelogram
