what is biometric data??
biometric data is the personal data such as the fingerprints or retina scan of a person.
it is used for security and to prevent hacking.
it is almost impossible to replicate biometric data

I think I can help you with this. Floor turtles are extremely easy. Suppose you have to move forward 100 (towards the left) and then up 50. You would write this in the following order:
>Pen down
>Forward 100
>Right 90
>Forward 50

If you had to go down 50 then:

>Pen down
>Forward 100
>Left 90
>Forward 50

Hope that helped .

For the first one the answer is:
>Pen Down
>Repeat 8 (Since it's an octagon)
>Right 90
>Forward 100
>Left 45 (The angle is given)
>End repeat

2nd one is:
>Pen Down
>Left 90
>Repeat 8
>Forward 60
>Right 45
>End repeat

Both of them aren't left, only the 2nd one is left.

But how come both of them are different is what I don't understand, both of them have the exact same shape... :/

Oh, if you look at where the starting point the pen is they both are different. For one you have to go left first while the other is right. It's kinda hard to explain over the internet but you could try printing a paper and rotating it to see which way would make sense haha.
