An obtuse angle is any angle that is between 91 degrees and 179 degrees. It can be added to a supplementary acute angle to form a straight line.
a line with an angle in it would technically be 2 linesA circle has a sum of angles that add up to 360 degrees and it is not a straight line.
Yes because angles on a straight line add up to 180 degrees
An angle can have up to 180 degree's. A circle can have up to 360 degrees. An angle with 180 degrees is a straight line. If you went any farther than it would change into a 179 degree angle, and so on.
Its realy easy if you think about it, Exterior angle = 180-178 = 2° because the interior and exterior angle add together make a straight line. All the exterior angles add up to 360° so if each exterior angle is 2° then the number of corners is 360÷2=180 and the number of sides is also 180. yeyyy i is goood by da SEXY SWMR ( secret identity )
