Morphology
isosceles = iso + sceles
Formed from Greek combining forms ('iso-' = equal + 'sceles' = leg) that are not productive standalone English words, so an average B1 learner cannot reliably derive the meaning from the parts.
Etymology
Isosceles comes from Greek parts iso- meaning 'equal' and -sceles meaning 'leg'. So an isosceles triangle has two 'equal legs', which explains why two of its sides are the same length.
