180 degrees.
What is the sum of the interior angles of a three-sided polygon?
The 3 interior angles of a 3 sided polygon which is a triangle add up to 180 degrees.
What 3 sided polygon has one obtuse angle?
An obtuse triangle.
What is sum of the interior angles of a polygon with three sides?
the sum of the interior angles of a 3 sided polygon is = 180 degrees. the sum of the interior angles of any polygon is given by 540/n. in this case n is = 3

What is the interior angle of a 11 sided polygon?
147 3/11
What 3 sided polygon has one obtuse angle?
An obtuse triangle.
What is the sum of the measures of the interior angles of a 1 sided polygon?
There is no such polygon because a polygon must have 3 or more sides.
What is sum of the interior angles of a polygon with three sides?
the sum of the interior angles of a 3 sided polygon is = 180 degrees. the sum of the interior angles of any polygon is given by 540/n. in this case n is = 3
A 3 sided polygon with 1 angle greater than 90?
It can be an obtuse triangle.
What is the sum of the angle measures of a 17 sided polygon?
Heres a good trick to figuring out the sum of the angles of an "n" sided polygon. It's common knowledge that a triangle (3 sides) has a sum of 180 degrees and a square (4 sides) is 360 degrees. You can infer that a pentagon (5 sides) has a sum of 540 degrees. So the equation to figure out the sum of all the angles of an "n" sided polygon is 180*(n-2). So in your case n = 17 so the equation becomes 180(17-2) = 2700 degrees
Why a triagle is always 180 degrees?
That is the angle sum of all three angles. This is a pattern in all polygons. Every time you add a side to a polygon, it's angle sum adds by "180". Since a two sided polygon is not possible, the tree sided triangle starts with 180 degrees. For example, an equilateral triangle will always have 60 degrees as the degrees for one edge, because 60 times 3 will equal 180. Quadrilaterals will have 360 degrees as an angle sum, and so on.
Does a 40 sided polygon have 6840 diagonals?
The sum of the angles of a regular n-sided polygon is equal to (n - 2) x 180 degrees.Therefore, the sum of the angles of a regular 40-sided polygon (tetradecagon) is equal to (40 - 2) x 180 = 6840 degrees. Therefore, 6840 refers to the sum of the degrees, not the number of diagonals.The number of diagonals of an n-sided polygon is given by n(n-3)/2. So a 40-sided polygon has 40*37/2=740 diagonals.
What is a 3 - sided polygon with one right angle and no equal sides?
A right scalene triangle.
