Climb north face of Everest made up of different sides (7)

Ross

I believe the answer is:

scalene

I'm a little stuck... Click here to teach me more about this clue!

'up of different sides' is the definition.
I can't tell whether this definition defines the answer.

'climb north face of everest' is the wordplay.
'climb' becomes 'scale' (scaling is a kind of climbing).
'north' becomes 'n' ('N' can be a synonym of 'north').
'face of' suggests taking the first letters.
The first letter of 'everest' is 'e'.
'scale'+'n'+'e'='SCALENE'

'made' is the link.

Can you help me to learn more?

(Other definitions for scalene that I've seen before include "(Of triangle) with each side of a different length" , "(Of triangle) with no sides equal" , "Having no sides for a match" , "Describing a triangle with unequal sides" , "(Of triangle) having three unequal sides" .)
