Question

What is the sum of all the internal angles of a square?

• A. 180°
• B. 360°
• C. 270°
• D. 320°

Hint:

The sum of the interior angles of any quadrilateral is 360°.

Answer 1

The Correct Option is B

Step 1: Understanding the Sum of Internal Angles.
The sum of the internal angles of any quadrilateral (including a square) is always 360°. This is derived from the formula for the sum of interior angles of a polygon: \[ \text{Sum of interior angles} = (n
- 2) \times 180°, \] where \( n \) is the number of sides (4 for a square). Thus, \[ (4
- 2) \times 180° = 360°. \] Step 2: Verifying the Options.

- Option (1): The sum of the interior angles of a square is 360°, not 180°.
- Option (2): The sum of the interior angles of any quadrilateral, including a square, is 360°.
- Option (3): 270° is incorrect.
- Option (4): 320° is incorrect. Conclusion:
Therefore, the correct answer is (2) 360°.
