Every quadrilateral can be inscribed in a circle . True/ False
![**Question:**
Every quadrilateral can be inscribed in a circle.
- ( ) True
- (•) False
**Explanation:**
In a cyclic quadrilateral (a quadrilateral that can be inscribed in a circle), the opposite angles must add up to 180 degrees. However, not all quadrilaterals have this property. Only those that satisfy this condition can be inscribed in a circle.
For further understanding, consider the following types of quadrilaterals:
1. **Square** - Can be inscribed in a circle.
2. **Rectangle** - Can be inscribed in a circle.
3. **Rhombus** - Cannot always be inscribed in a circle unless it is also a square.
4. **Parallelogram** - Cannot always be inscribed in a circle unless it is a rectangle or square.
5. **Trapezium** - Only certain trapeziums, such as isosceles trapeziums, might be inscribed in a circle.
Thus, the answer is **False** because not all quadrilaterals meet the criteria to be inscribed in a circle.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ffa3a928b-a4ee-4ef3-a9f6-a45e729644b2%2F527eb066-c5ed-429b-8b5a-e8b86e643ba8%2Faf3cfo_processed.jpeg&w=3840&q=75)
