Statement 2:
Sum of interior angles of a polygon = (n - 2) × 180 = (2n - 4) × 90
∴ Statement 2 is false
Statement 1:
Sum of interior angles of the polygon = n × 90° [∵ All angles are right angles]
(2n - 4) × 90 = n × 90
2n - 4 - n
∴ n = 4.
Statement 1 is true

Statement 1: The polygon has exactly four sides
Statement 1 states that the polygon has exactly four sides. This means that it is a quadrilateral.
Statement 2: The sum of the angles of a polygon having n sides is (3n - 8) right angles.
Statement 2 gives a formula for finding the sum of the angles of a polygon with n sides. According to this formula, the sum of the angles is equal to (3n - 8) right angles.
Explanation:
To determine the correctness of the statements, let's analyze each statement separately.
Statement 1:
If the angles of a polygon are all equal and each angle is a right angle, the polygon would have four right angles. This implies that the polygon is a quadrilateral, as all quadrilaterals have four sides. Therefore, Statement 1 is true.
Statement 2:
Statement 2 provides a formula for calculating the sum of the angles of a polygon with n sides. The formula (3n - 8) is derived from the fact that the sum of the interior angles of a polygon with n sides is equal to (n-2) times 180 degrees. In this case, since each angle is a right angle (90 degrees), we divide the sum by 90 to find the number of right angles. This results in (n-2) right angles. However, since each angle in the given polygon is a right angle, the sum of the angles will be equal to n right angles. Therefore, the formula (3n - 8) is not applicable in this case. Hence, Statement 2 is false.
Conclusion:
Based on the analysis, we can conclude that Statement 1 is true but Statement 2 is false. Therefore, the correct answer is option (C) - Statement 1 is true but Statement 2 is false.
