alleryWhich set of interior angles describes a rectilinear polygon?
AOnly 90° or 270°
BOnly 60° or 300°
COnly 120° or 240°
DOnly 45° or 135°
Answer & Solution
Correct answer: A. Only 90° or 270°
1. Rectilinear polygons have sides meeting at right angles.
2. So each interior angle is 90° or 270°.
3. Angles like 60° or 120° would not be right angles.
