Draw angles that approximate each of the following measures.

1. $50°$

   Hint (a):

   This is a little more than $45°$.

2. $170°$

   Hint (b):

   This is a little less than $180°$.

3. $190°$

   Hint (c):

   This is a little more than $180°$.

4. $270°$

   Hint (d):

   Remember that a $360°$ angle is at the center of an entire circle. Notice that $270° + 90° = 360°$.
   Also, $180° + 90° = 270°$. What should this look like?
