A chevron (arrowhead) is a quadrilateral with one angle of more than 1800.
An angle measuring more than 90 degrees is obtuse. An angle measuring less than 90 degrees is acute. An angle measuring 90 degrees is right.
No.
obtuse angle
obtuse angle
An acute angle is an angle measuring less than 90 degrees. An obtuse angle is an angle which is more than 90 degrees, but less than 180. A reflex angle is an angle which measures more than 180 degrees, but less than 360. So an angle of 97 degrees is an obtuse angle.
obtuse angle, definitely.
An angle more than 90o and less than 180o is an obtuse angle. An angle more than 180o is a reflex angle.
Obtuse angle
A general quadrilateral or a kite.
