What is the measure of each interior angle in a regular eight-sided polygon?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 135°.
Sum of interior angles of n sided polygon = (n – 2) × 180°
For n = 8, Sum of interior angles = (8 – 2) × 180° = 6 × 180° = 1080°
Each interior angle = 1080°/8 = 135°
