Total interior angles: (100-2)*180 = 17,640 degrees
a right angle is 90 degrees. 100% of the time.
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.
A straight line in angles represents 180 degrees.

Exterior angles add up to 360 degrees Interior angles add up to 17,640 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.
360 degrees
Angles are measured in degrees. It is degress 100% sure.
A parallelogram has 2 sets of equal sides.That means that there are 2 sets of the same angles.If one angle is 100 degrees,the angle diagonal of it is also 100 degrees.So as long as you know one angle you can calculate the rest since all the angles have to add up to 360 degrees.So if there are three unknown angles but one is 100 degrees.One of the unknown angles is also 100 degrees.And since that equals to 200 degrees,minus 360 by 200 and you get 160 which is the combined degrees of the last two angles which are the same.So the last two angles are both 80 degrees.
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.
A straight line in angles represents 180 degrees.
External angles would total 360 degrees; internal angles would total 14,400 degrees.
The total when you add up the three angles in a triangle is 180 degrees.If one angle is 100 degrees, then the total of the other two angles is 80 degrees. This means that those two angles must SMALLER than 90 degrees.So a triangle with an angle of 100 degrees cannot be a right triangle.
