First I will ask 'does your card show just an angle?' because there are only a few cards that do have them.
If the answer is "YES" then you can remove 17 cards which are shapes out of 24 cards.
The next question I will ask, " is it an Right angle." if he saids 'yes' then I can remove 4 more cards and I have 3 left.
Is it a triangle? if they say 'yes', then I would ask, is the bottom line shorter than the top one? If they say 'no', then there will be one card left, which is the right angled triangle.
