Question from Nazrul, a teacher: Is zero degree an acute angle? Please explain. |
I would say a zero degree angle is an acute angle for the following reasons:
- A zero degree angle is formed by two rays that share a vertex and point in the same direction.
- According to Euclid's Elements, Book I, Definition 12. "An acute angle is an angle less than a right angle."
Hope this helps,
Janice
