Im having a issue where Im getting the correct answer but it will not let me continue. It keeps asking if I created a instance called my_triangle which I have. Its frustrating when this happens as Ive encountered throughout the course but Im really stumped to what it wants me to do.

In my eyes my code is correct but maybe Im wrong… any help is much appreciated

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