The level completes with a minimal code that describes the triangle class. The check angles method does not have to be there to pass the level. Also in next levels you can ignore the times where you have to use check angles method.

I should not pass this level because I did not write the check angles method

```
#THIS PASSES THE LEVEL
class Triangle(object):
number_of_sides = 3
def __init__(self, angle1, angle2, angle3):
self.angle1 = angle1
self.angle2 = angle2
self.angle3 = angle3
###THIS SHOULD BE REQUIRED TO PASS:
class Triangle(object):
number_of_sides = 3
def __init__(self, angle1, angle2, angle3):
self.angle1 = angle1
self.angle2 = angle2
self.angle3 = angle3
def check_angles(self):
if self.angle1 + self.angle2 + self.angle3 == 180:
return True
else:
return False
```
