270 degrees
If you want to ask questions about the "following", then I suggest that you make sure that there is something that is following.
540 degrees.
There is no such figure as a 20 degrees polygon.
A four sided figure is known as a quadrilateral and its 4 interior angles add up to 360 degrees
Total of exterior angles of a plane figure is always 360 degrees so 360/20 = 18 degrees. Alternatively interior angles of n sided figure always total (2n -4) right angles. In this case n = 20 so total interior angles = 36 right angles ie 3240 degrees and each angle = 3240/20 ie 162 degrees. Subtracting this from 180 gives 18 degrees. QED
90 degrees
An obtuse angle.
You might be able to figure this out for yourself, based on the following information:* The angles of a triangle must add up to 180 degrees. * A right angle has a measure of 90 degrees.
A straight angle
1080 degrees
What is the MJK math
The interior angles measure 360 degrees.
I believe it's 1,800 degrees.
Each angle has a measure of 120 degrees
An isosceles triangle.
