what is the maximum number of possible right angles in a pentagon?

OpenStudy (anonymous):

The sum of the exterior angles of a pentagon must add up to \(360^\circ\). How many \(90^\circ\) ext. angles can you have?

OpenStudy (highschoolmom2010):

4......oh wow i just had the biggest brain fart ever XD

OpenStudy (anonymous):

Does that make sense now?

OpenStudy (highschoolmom2010):

yea

OpenStudy (highschoolmom2010):

it is 4 correct?

OpenStudy (anonymous):

It's not 4, no. If you had 4 right angles, you'd end up with a square.
