Step-by-Step Solution
A kite has two pairs of adjacent equal sides. Its diagonals are perpendicular, and one diagonal bisects the other.
Answer: A) Kite
Which quadrilateral is defined by having two pairs of adjacent (consecutive) sides equal?
Class 8Understanding QuadrilateralsQuadrilaterals
Key idea: The quadrilateral family tree
Order from most general to most special:
```
Quadrilateral
├── Trapezium (one pair of parallel sides)
├── Kite (two pairs of adjacent equal sides)
└── Parallelogram (two pairs of parallel sides)
├── Rectangle (4 right angles)
│ └── Square (4 right angles + all sides equal)
└── Rhombus (4 equal sides)
└── Square (also)
```
A square is BOTH a rectangle and a rhombus — it's the most special kind of parallelogram. A rectangle and a rhombus are both parallelograms. Trapeziums and kites are quadrilaterals but not parallelograms.
