Mine doesn't work, someone can help?

It says: "*AttributeError: Equilateral instance has no attribute 'angle1'*" when it's clear in the instruction that we should create an `__init__()`

function with **only the parameter self** !

```
class Triangle():
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(90, 30, 60)
class Equilateral(Triangle):
angle = 60
def __init__(self):
self.angle1 == self.angle
self.angle2 == self.angle
self.angle3 == self.angle
my_triangle = Triangle(90,30,60)
my_equilateral = Equilateral()
print my_triangle.number_of_sides
print my_triangle.check_angles()
print my_equilateral.number_of_sides
print my_equilateral.check_angles()
```
