Using Circles to Find Angle Measures

Find the angle measures:

If, in the figure above $m\angle{2}=25$ and $m\angle{1}=95$, what is:

1. $m\angle{5}$
2. $m\angle{4}$
3. $m\angle{6}$
4. $m\angle{3}$

If, in the figure above $m\angle{1}=100$ and $m\angle{6}=40$, what is:

5. $m\angle{2}$
6. $m\angle{3}$
7. $m\angle{4}$
8. $m\angle{5}$

If, in the figure above $m\angle{3}=90$, what is:

9. $m\angle{6}$
10. $m\angle{2}+ m\angle{4} $
11. $m\angle{1}+ m\angle{5} $
12. $m\angle{2}+ m\angle{4} + m\angle{6} $
