Explanation:
I genuinely hope I've interpreted your question correctly, please reach back if I didn't. I think its asking for the type of angle and not the degree.
1. acute
2. right
3. I can't see the full angle, but remember this:
below 90 acute (looks more closed in)
exactly 90 right (Looks like the letter L)
above 90 obtuse (Looks more open)
use the little radius (circle) to determine the angle (a square is an instant sign of a right angle)
4. right
5. acute
6. obtuse
7. acute
8. obtuse
9. acute
10. obtuse
11. I can't see it at all
