Give a rule in words to find the number of nonoverlapping triangles in a polygon

The number of non overlapping triangle in a polygon is 2 less than the number of sides.

Step-by-step explanation:

Consider the provided information.

The sum of all interior angle of the polygon with n sides is 180(n-2).

The above formula is related with the number of non overlapping triangles in a polygon.

As we know that the sum of all interior angle of a triangle is 180°. That means 180 in the above formula is represents the sum of interior angle of triangle.

The (n-2) represents the number of non overlapping triangles in a polygon with n side.

Thus, we can say that the number of non overlapping triangle in a polygon is with n side is n-2.

In words the rule is: The number of non overlapping triangle in a polygon is 2 less than the number of sides.

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.

he answer is x=1x3 because x=1 to x=3
