An '''angle''' was described by [[Euclid]] as "the inclination to one another of two lines which meet each other in the same [[plane]]." An angle is a bend formed by two intersecting [[line]]s or [[Line Segment]]s.
An '''angle''' was described by [[Euclid]] as "the inclination to one another of two lines which meet each other in the same [[plane]]." An angle is a bend formed by two intersecting [[line]]s or [[Line Segment]]s.
Angles are described as being [[Acute angle|acute]] (less than ninety [[degree]]s), right angles (ninety degrees exactly), [[Obtuse Angle|obtuse]] (greater than ninety degrees but less than one hundred eighty degrees), and reflex (over 180 degrees). A one-hundred-eighty degree angle is a straight line.
Angles are described as being:
* [[Acute angle|acute]] (less than 90 [[degree]]s)
* [[Right angle|right]] (90 degrees exactly)
* [[Obtuse angle|obtuse]] (greater than 90 degrees but less than 180 degrees)
* [[Reflex angle|reflex]] (over 180 degrees)
A 180 degree angle is a straight line.
