Too thick to get the right angle? (6)
I believe the answer is:
obtuse
This could be a double definition.
'too thick' is the first definition.
'obtuse' can be an answer for 'thick' (I've seen this in another clue). I'm not sure about 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 not certain 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 "Blunt, not sharp or pointed" , "Angles could be" , "Blunt, not sensitive" , "not acute?" , "A 3dn between 90 and 180 degrees" .)
