You can have an infinite number of triangles in a polygon, it would really depend on the size of the triangles you are trying to fit in.
If on the other hand you mean that triangles are made by joining the point of the polygon to make triangles then it's the number of sides minus two.

If n equals the number of sides in a polygon what equals the number of trianges within the polygon?
There can be no formula for the number of triangles within the polygon. Any triangle can be split into two by a line from one of the vertices to the opposite side. Thus the number of triangles can be increased by one by simply splitting one triangle. And then THAT triangle can be split in two, and the that one, ...
How can you find the number of diagonals in a polygon?
The formula is: 0.5*(n2-3n) where n is the number of sides of the polygon
What is the least number of angles a polygon can have?
3, it's called a triangle.
Why the sum of angles in triangle is 180 degree?
Formula for finding the total sum of interior angles of any polygon is: (number of sides-2)*180 A triangle has 3 sides. (3-2)*180 = 180 degrees
How do you get the total number of diagonals of a polygon?
The formula is: 0.5*(n2-3n) = diagonals whereas n is the number of sides of the polygon

How many diagonals in triangle to dodecagon?
The formula is: 0.5*(n2-3n) = number of diagonals when n is the number of sides of the polygon
A polygon with the least possible number of sides?
A polygon with the least number of sides is a triangle (3 sides)
What is the area of a 2d shape?
The area of a polygon is calculated using different formula depending on the number of sides of the polygon. The formula for a quadrilateral is length times width, the formula for a circle is pi time the square of the radius, and the formula for a triangle is base times height, divided by two.
Is a triangle a polygon?
Yes, a triangle is a polygon.A polygon is any closed figure made up of 3 or more line segments. The triangle qualifies, and it is the "most simple" polygon as it has the least number of sides.A triangle is most certainly not a ploygon. However, it is a polygon.
What is the sum of the interior angles?
The sum of the interior angles for any polygon can be found by the formula 180 degrees multiplied by n-2, where 'n' is the number of sides of a polygon. If the polygon is a triangle, then the sum of the interior angles is 180 degrees because n is equal to three, the number of sides in a triangle.
What does a three sided polygon add up to?
Since a three sided polygon is another name for a triangle. We would use the formula of * (n - 2)180 = degrees of the polygon * n = number of sides of the polygon * (3(sides) - 2)180 * (1)180) * = 180o
Does a polygon have three sides?
A polygon can have any number of sides above three. The name of a three-sided polygon is a triangle.
How can you find the number of diagonals in a polygon?
The formula is: 0.5*(n2-3n) where n is the number of sides of the polygon
What is the polygon with the least number of sides?
the triangle, unless you can show us a polygon with only two sides
Why the sum of angles in triangle is 180 degree?
Formula for finding the total sum of interior angles of any polygon is: (number of sides-2)*180 A triangle has 3 sides. (3-2)*180 = 180 degrees
Where did the polygon name for triangle come from?
The name of a triangle came from the number of angles it has, 'tri' meaning three.
