Select the incorrect match.

Options

A. One pair of parallel side - Trapezium
B. Parallelogram with 4 right angles - Rectangle
C. Parallelogram with 4 sides of equal length - Rhombus
D. A quadrilateral with opposite sides equal - Kite

Answer

To solve the question of selecting the incorrect match, we will analyze each option step by step.

### Step 1: Analyze the first option
- **Statement**: "One pair of parallel sides in a trapezium."
- **Explanation**: A trapezium (or trapezoid) is defined as a quadrilateral that has at least one pair of parallel sides. Therefore, this statement is true.

### Step 2: Analyze the second option
- **Statement**: "A rectangle is a parallelogram."
- **Explanation**: A rectangle is a special type of parallelogram where all angles are 90 degrees, and opposite sides are equal and parallel. Thus, this statement is also true.

### Step 3: Analyze the third option
- **Statement**: "A parallelogram with four sides of equal length is a rhombus."
- **Explanation**: A rhombus is indeed a type of parallelogram where all four sides are of equal length. This statement is true as well.

### Step 4: Analyze the fourth option
- **Statement**: "A kite is a quadrilateral with opposite sides equal."
- **Explanation**: A kite is a quadrilateral with two pairs of adjacent sides that are equal, but the opposite sides are not equal. Therefore, this statement is false.

### Conclusion
The incorrect match is the fourth option: "A kite is a quadrilateral with opposite sides equal."
