it's asking if I initialized my triangle with 3 sides...which I did. I'm not sure what's wrong here.

```
class Triangle(object):
def __init__(self, angle1, angle2, angle3):
self.angle1 = angle1
self.angle2 = angle2
self.angle3 = angle3
number_of_sides = 3
def check_angles(self, angle1, angle2, angle3):
if angle1 + angle2 + angle3 == 180:
return True
else:
return False
my_triangle = Triangle(90, 30, 60)
print my_triangle.number_of_sides()
print my_triangle.check_angles()
```
