Step 1: Understanding the Angle Sum of a Quadrilateral.
The sum of the interior angles of any quadrilateral is always 360°. This can be divided into four right angles, as each right angle measures 90°. Step 2: Verifying the Options.
- Option (1): Three right angles would sum to 270°, which is incorrect.
- Option (2): Five right angles would sum to 450°, which is incorrect.
- Option (3): Four right angles add up to 360°, making this the correct answer.
- Option (4): Six right angles is incorrect.
Conclusion:
Therefore, the correct answer is (3) Four right angles.
