alleryWhat is a non-convex polygon, in terms of a line crossing it?
ANo line crosses it twice
BSome line meets it 3+ times
CEvery line meets it once
DAll angles are equal
Answer & Solution
Correct answer: B. Some line meets it 3+ times
1. For a convex polygon, any line through it meets the boundary exactly twice.
2. A non-convex polygon has some line meeting the boundary more than twice.
3. Equal angles describe equiangular shapes, not convexity.
