i think its false
OpenStudy (anonymous):
suppose the quadraleral has 2 angles that are 45degrees and 2 that are 135 drgrees
OpenStudy (anonymous):
basically any figure with 2 sets of angles that are not 90 degrees. so 2 1 degree and 2 179 degree figure
OpenStudy (anonymous):
does that make sense?
OpenStudy (anonymous):
yes, thank you!
