Starting out: triangle example: Text and code doesn't fit image

[hacklschorsch]

Is your content edit request related to a problem? Please describe.

I stumbled over the right triangle example in starting out: The text/code is not consistent with the image here

The image suggests (a) being the longer leg, the text/code has (b) be the longer leg.

Describe the solution you'd like

Changing the text/code is probably easier than changing the image?

Describe alternatives you've considered

I thought opening a PR but wasn't sure if this is a mistake at all or maybe if I'm mistaken - also, what's the best solution?

Additional context

(none)
