Because it is easier to use. If a right angle were to be 100 degrees when you compare it to 90, 90 has a lot more factors than 100. It's probably in the ancient days when people made it like that.
None All shapes would be 360 degrees not 380 look at a circle , square, octagon etc.
360 degrees
If A and B are the angles, then A + B = 180 and A - B = 20 So that 2A = 200 ie A = 100 and then B = 80 So the two angles are 100 and 80 degrees.
Total interior angles: (100-2)*180 = 17,640 degrees

Oh, dude, those are angles, not shapes. But if you want to get technical, an 80-degree angle is an acute angle because it's less than 90 degrees, and a 100-degree angle is an obtuse angle because it's more than 90 degrees. So, like, they're both angles, not shapes.
Well, darling, that quadrilateral is a simple convex quadrilateral because all the interior angles add up to 360 degrees. It's also a quadrilateral with no parallel sides or right angles, so it's not a square, rectangle, parallelogram, or rhombus. Just a sassy little quadrilateral with angles of 110, 100, 80, and 70 degrees.
They are four angles which are equal. They could be 4 angles of a pentagon measuring 100 degrees, where the fifth measures 40 degrees.
Exterior angles add up to 360 degrees Interior angles add up to 17,640 degrees
360 degrees
Angles are measured in degrees. It is degress 100% sure.
The sum of the measures of the angles in any triangle in the plane is 180 degrees. If two angles are 15 and 85 then their sum is 100 degrees and 180-100=80 degrees
If A and B are the angles, then A + B = 180 and A - B = 20 So that 2A = 200 ie A = 100 and then B = 80 So the two angles are 100 and 80 degrees.
Total interior angles: (100-2)*180 = 17,640 degrees
A straight line in angles represents 180 degrees.
