Select the correct option.

Options

A. Two pairs of parallel sides - Trapezium
B. A rhombus with 4 right angles - Rectangle
C. Parallelogram with 4 right angles - Rectangle
D. None of these

Answer

To solve the question, we need to analyze the statements provided in the options and determine which one is correct. Let's break it down step by step:

### Step 1: Understand the Definition of a Trapezium
A trapezium (or trapezoid in some regions) is defined as a quadrilateral with at least one pair of parallel sides.

**Hint:** Remember that a trapezium has only one pair of parallel sides.

### Step 2: Analyze the First Option
The first option states that "two pairs of parallel sides make a trapezium." This is incorrect because a trapezium only requires one pair of parallel sides. If there are two pairs of parallel sides, the shape is a parallelogram, not a trapezium.

**Hint:** Think about how many pairs of sides need to be parallel for a shape to be classified as a trapezium.

### Step 3: Understand the Definition of a Rhombus
A rhombus is a type of quadrilateral where all four sides are of equal length and opposite sides are parallel.

**Hint:** Recall that a rhombus does not necessarily have right angles.

### Step 4: Analyze the Second Option
The second option suggests that a rhombus has right angles. This is incorrect because a rhombus can have angles that are not 90 degrees. If a rhombus has all right angles, it is specifically a square.

**Hint:** Consider the properties of a rhombus and whether it can have right angles.

### Step 5: Understand the Definition of a Rectangle
A rectangle is a quadrilateral with four right angles and opposite sides that are equal and parallel.

**Hint:** Remember that all angles in a rectangle are right angles.

### Step 6: Analyze the Third Option
The third option states that "the parallelogram with four right angles is called a rectangle." This is correct because a rectangle is defined as a parallelogram that has four right angles.

**Hint:** Think about the properties of a rectangle and how it relates to parallelograms.

### Conclusion
After analyzing all the options, the correct answer is:
**Option number 3: The parallelogram with four right angles is called a rectangle.**

**Final Answer:** Option number 3.
