it measures 360 degrees
Ninety Degrees
A nonagon has 9 sides. It can have one or more 90 degree angles. If it is a regular nonagon then it has 180*7/9 for the interior angle measures which is 140 degrees.
Spheres are measured with solid angles (which are like two dimensional angles). These angles can be measure with square degrees or steradians. A sphere measures 129300/π square degrees (or about 41,253 square degrees). A sphere measures 4π steradians (or about 12.566 steradians.)
A 'right angle' looks like a corner, and measures 90 degrees.
it measures 360 degrees
If its a regular polygon and each interior angle measures 175.2 degrees then it will have 75 sides
Ninety Degrees
It has four 90 degree angles
20 degrees
A nonagon has 9 sides. It can have one or more 90 degree angles. If it is a regular nonagon then it has 180*7/9 for the interior angle measures which is 140 degrees.
3 interior angles and each of them measures 60 degrees
A square has 4 right angles. Right angles are 90 degree angles.4*90 degrees = 360 degrees
The sum of the measures of the interior angles is (n-2)*180 degrees, where n is the number of sides. Thus, if the sum of the interior angles is S, then n = S/180 + 2
Spheres are measured with solid angles (which are like two dimensional angles). These angles can be measure with square degrees or steradians. A sphere measures 129300/π square degrees (or about 41,253 square degrees). A sphere measures 4π steradians (or about 12.566 steradians.)
A 'right angle' looks like a corner, and measures 90 degrees.
A quadrilateral doesn't have degrees. It has four sides, four inside angles, four outside angles, a perimeter, and an area. If you add up the measures of all four outside angles, they add to 360 degrees. If you add up the measures of all four inside angles, they add to 360 degrees too.
