How are angles labeled?
Angles are labeled by specifying 3 points, with the center point being the vertex of the angle. This angle is NOT ∠BAC. Angles may be labeled with a single letter at the vertex, as long as it is perfectly clear that there is only one angle at this vertex.
How do you classify an angle?
Angles are classified according to their measures as follow:
- An acute angle is an angle whose measure is between 0∘ and 90∘.
- A right angle is an angle whose measure is 90∘.
- An obtuse angle is an angle whose measure is between 90∘ and 180∘.
- A straight angle is an angle whose measure is 180∘.
