An obtuse angle
A straight line of 180 degrees
u rotated 180 degrees will be upside down and will look like an n. Sometimes answers changes when you say I in a question to be a u. If you are talking about capital I, it will look the same rotated 180 degrees. i will look like an exclamation mark upside down
Yes
Well, honey, any shape that looks the same after a 180-degree spin is what we call a shape with 180 degrees rotational symmetry. So, we're talking about shapes like squares, rectangles, and even circles. Basically, if it looks just as good upside down, you've got yourself a shape with 180 degrees rotational symmetry.
Either a straight line or an about turn / about face.
A 180 Degree shape would be a line a straight line or diagnal like this: _____________
A straight line of 180 degrees
Anything you like - between 0 and 360 degrees. The only thing that you can say is that the sum of all the interior angles will be (7-2)*180 = 5*180 = 900 degrees.
Any value you like, between 0 and 360 degrees, other than 180 degrees. Any oair of interior and exterior angles must sum to 180 degrees.
Yes, if you turn a shape completely around to its original position it will look like its original position because it will be in its original position. For example if i take a trapezoid and turn it 180 degrees it does not look the same as it did before so it does not have rotational symmetry of 180 degrees.
Any angle that you like between 0 and 360 degrees. Possibly excluding 180 degrees since that is just a straight line.
Yes, 180 degrees is the same as a reflection in geometry. When a shape is reflected over a line, the angle formed between the original shape and its reflection can be measured, and for a line of reflection, this angle is 180 degrees. In essence, a 180-degree rotation or reflection produces a symmetrical image across the line of reflection.
It could be the shape of a triangle because its 3 interior angles add up to 180 degrees

a line or straight angle
UGLY
(sides-2)*180=the total angle of the shape. So octagon (8-2)*180=1080 Just like a triangle (3-2)*180
