In the following figures, which is not equi-quadrilateral?
Step 1: Understanding Equi
-Quadrilateral Shapes.
An equi
-quadrilateral is a quadrilateral with all sides of equal length. A square and rhombus are equi
-quadrilaterals, as all their sides are equal. A rectangle and parallelogram may have unequal sides.
Step 2: Verifying the Options.
- Option (1): A square has all sides equal, so it is an equi
-quadrilateral.
- Option (2): A rectangle has unequal adjacent sides, so it is not an equi
-quadrilateral.
- Option (3): A parallelogram with equal sides could be an equi
-quadrilateral if the sides are equal.
- Option (4): A rhombus has all sides equal, so it is an equi-quadrilateral.
Conclusion:
Therefore, the correct answer is (2) Figure of rectangle with length \( x \) and breadth \( y \).
