How many right angles are there in a rectangle ?

Answer

To determine how many right angles are there in a rectangle, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definition of a Rectangle**:
A rectangle is defined as a quadrilateral (a four-sided figure) where opposite sides are equal in length and all angles are right angles.

**Hint**: Remember that a quadrilateral has four sides and four angles.

2. **Identify the Angles in a Rectangle**:
A rectangle has four angles. Since it is defined as having right angles, we need to check the measurement of these angles.

**Hint**: Think about how many corners a rectangle has and what type of angles are formed at each corner.

3. **Measure the Angles**:
Each angle in a rectangle measures 90 degrees. This is the definition of a right angle.

**Hint**: Recall that a right angle is exactly 90 degrees.

4. **Count the Right Angles**:
Since all four angles in a rectangle are right angles, we can conclude that there are four right angles.

**Hint**: You can visualize or draw a rectangle to see all four angles clearly.

### Final Answer:
Thus, there are **4 right angles** in a rectangle.
