Too stupid to get the right angle? (6)
I believe the answer is:
obtuse
This could be a double definition.
'too stupid' is the first definition.
'obtuse' can be an answer for 'stupid' (similar in meaning). I'm not certain of the 'too' bit.
'the right angle?' is the second definition.
'obtuse' can be an answer for 'angle?' (obtuse angle is a kind of angle). I am unsure of the 'the right' bit.
'to get' acts as a link.
Can you help me to learn more?
(Other definitions for obtuse that I've seen before include "Annoyingly insensitive" , "Slow, dull" , "boneheaded?" , "A 3dn between 90 and 180 degrees" , "(Of angle) between 90deg and 180deg - dull" .)
