An icosagon is a 20 sided polygon and its interior angles add up to 3240 degrees
The sum of the interior angles of a rectangle is 360 degrees.
The interior angles of an 8 sided octagon add up to 1080 degrees
360 degrees
The sum of the internal angles of any triangle is 180 degrees. Any rectangle has four 90 degree internal angles, totalling 360 degrees.
360 degrees
The 4 angles of a rectangle add up to 360 degrees
Since every rectangle has 4 internal 90-degree angles ("right angles"), the sum of the angles of any rectangle is 90o+90o+90o+90o, equaling 360 degrees.
4 right angles = 90x4 = 360 degrees
The internal angles sum to 360 degrees.
Oh, what a lovely question! You see, a rectangle has four angles, each measuring 90 degrees. When we add all these angles together, we get a total of 360 degrees. It's like a happy little math puzzle that fits together perfectly!
Well, since each angle of a rectangle is 90 degrees, and a rectangle has 4 angles, a rectangle's interior angles added together is 360.
