when my 3rd grade teacher taught us about geometry she gave us little tips for remembering which one was which.
Obtuse and open
acute is "a cute" and little angle
when i associated anything with cute those days it was bunnies.
i do not know why.
well when u make an angle you know you have to make a square(for a right angle) or a curved line(for acut and obtuse angles), i always tried to find the little bunnies and neon open signs inside of the angles on tests.
