How can you combine multiple traces into the frame?

I need to make a shape that is essentially a triangle, if you added a line protruding outward from each vertices.

If I am not animating it, I can just make multiple traces and combine the traces:

```
trace1 = go.Scatter3d(
x=[x[0,0],x[0,3]],
y=[y[0,0],y[0,3]],
z=[z[0,0],z[0,3]])
trace2 = go.Scatter3d(
x=[x[0,1],x[0,4]],
y=[y[0,1],y[0,4]],
z=[z[0,1],z[0,4]])
trace3 = go.Scatter3d(
x=[x[0,2],x[0,5]],
y=[y[0,2],y[0,5]],
z=[z[0,2],z[0,5]])
trace4 = go.Scatter3d(
x=[x[0,0],x[0,1],x[0,2],x[0,0]],
y=[y[0,0],y[0,1],y[0,2],y[0,0]],
z=[z[0,0],z[0,1],z[0,2],z[0,0]])
data = [trace1, trace2, trace3, trace4]
```

But when animating, I can plot the triangle shape, but I canâ€™t see how to add on the additional lines.

```
fig = go.Figure(frames=[go.Frame(data=go.Scatter3d(x=[x[k,0],x[k,1],x[k,2],x[k,0]],
y=[y[k,0],y[k,1],y[k,2],y[k,0]],
z=[z[k,0],z[k,1],z[k,2],z[k,0]]),
name=str(k))
for k in range(nb_frames)])
fig.add_trace(go.Scatter3d(x=[x[0,0],x[0,1],x[0,2],x[0,0]],
y=[y[0,0],y[0,1],y[0,2],y[0,0]],
z=[z[0,0],z[0,1],z[0,2],z[0,0]]))
```
