This depends on the polygon.For a triangle (3-sides) : maximum 1 obtuse angle.Quadrialteral (4-sides): maximum 3 obtuse angles.For polygons with more sides, it is possible for all angles to be obtuse.
None normally but if it is in the shape of an isosceles triangle then it will have 2 equal sides.
An obtuse angle is any angle larger than 90°. An obtuse angle is not assigned any specific value.
An obtuse angle is only one angle, however if you meant 'how many degrees?' then an obtuse angle contains more than 90 and less than 180 degrees..
Greater than 90 but less than 180 degrees
An obtuse angle is greater than 90° but less than 180°. Any angle within that range is considered to be obtuse.
It ha one right angle, two obtuse angles and one acute angle
An obtuse angle is an angle measuring between 90 and 180 degrees
if it is over 90 degrees its obtuse.
All angles are made up when two lines or sides vertexes or intersection points, I think.
An obtuse angle can be any angle over 90 degrees and below 180 degrees (anything over that is a reflex angle)
An obtuse angle has more than 90 degrees. An obtuse angle is larger than a right angle (90 degrees) and smaller than two right angles (180 degrees), so an obtuse angle is between 90 and 180 degrees.
