alleryA rectilinear polygon has every interior angle equal to which values?
A60 or 120 degrees
B90 or 270 degrees
C45 or 135 degrees
D180 or 360 degrees
Answer & Solution
Correct answer: B. 90 or 270 degrees
1. In a rectilinear polygon the sides meet at right angles.
2. Its interior angles are therefore 90 or 270 degrees.
3. The other pairs do not describe right-angled corners.
