N-2X180, N=Number of sides, for a triangle, 3-2=1X180=180, so the sum of the interior angles are 180 degrees. Also, to let you know, you can memorize this pattern, a triangle has 180 degrees in it, and so every time you add a side, you must add 180 degrees.

What do the interior angles of a polygon equal?
The total for the interior angles depends on the number of sides. The formula for the total of interior angles of an n-sided polygon is sum =180(n-2). This is 180 degrees for triangles, 360 degrees for quadrilaterals, and 540 degrees for pentagons.
What is the formula for finding angles for quadrilaterals?
(number of sides-2)*180 = sum of interior angles
What is area formula of an irregular hexagon?
There is no standard formula. It is necessary to partition the irregular hexagon into more convenient shapes such as triangles and quadrilaterals, find their areas and sum the results.
What is the formula of a quadrilateral?
There is no formula that covers all aspects of quadrilaterals. There are different formulae for its area, or its angles.There is no formula that covers all aspects of quadrilaterals.

How many triangles does a polygon have?
It varies regarding the number of sides of polygon.Additional Information:-The formula is for any polygon: n-2 = number of interior triangles whereas n represents the number of sides of the polygon
What is the polygon whose interior angles equal 180 degrees?
It is a triangle. The formula for the total of interior angles in an n-sided polygon is 180(n-2). This is 180 degrees for triangles, 360 degrees for quadrilaterals, and 540 degrees for pentagons.

Do you calculate the interior angles of regular and irregular polygons the same way using the number of sides - 2 times 180 degrees n-2180 sum of interior angles. A Pentagon would 5-2?
All triangles have 180 degrees, all quadrilaterals have 360 degrees, no matter what the kind of triangle or quadrilateral. The formula would hold true for all polygons. Prove this by drawing diagonal lines in a polygon (do not cross one diagonal with another) to divide the polygon into quadrilaterals and/or triangles. Then add the degrees in the quadrilaterals and triangles in your polygon. This should give you the correct number of degrees. If you have a many sided polygon, it is necessary to use the formula, because the figure would be very difficult to draw. Formula- Number of sides minus 2, times 180 degrees. (n-2) X 180= degrees in a polygon

Why is it that quadrilaterals add up to 360 degrees?
Because they comply with the formula for the interior degrees of a polygon which is: (number of sides-2)*180 = interior degrees A quadrilateral has 4 sides so (4-2)*180 = 360 degrees
Why do triangles have 180 degrees?
Because the formula for the interior degrees of a polygon is (number of sides -2)*180 = sum of interior angles. A triangle has 3 sides so: (3 -2)*180 = 180 degrees
