angle and straight angleThe definition of an angle is a distance between two noncollinear rays with common endpoint called vertex. #2 20081126 17:31:21
Re: angle and straight anglecollinear represents two lines lying on the same straight line. Character is who you are when no one is looking. #3 20090915 02:20:33
Re: angle and straight angletwo rays whose measurement is 180 degrees does not mean that they are collided or connected. Therefore, there is no vertex exists. I am looking for an answer for the definition of angle and straight angle. Thanks!
