In any polygon, the sum of the angles is given by the formula:
a = 180(n-2) where a = sum of angles and n = number of sides.
In a regular polygon (a shape where each angle and side is the same size / length), you can therefore work out that each angle is the total of the angles in the shape divided by the number of sides or:
a = 180(n-2)/n where a = size of the angle and n = number of sides
Alternatively, it is possible to work out the size of the angles by dividing 360 by the number of sides and subtracting from 180 or:
a = 180 - 360/n (letters as before)
This is because the external angles of a shape must equal 360 so the size of each is 360 divided by the number of sides. Therefore, the internal angle is 180 - the external angle.
NB: all answers are in degrees

What angle have 10 sides?
No angle has 10 sides. An angle has two sides.
What is the formula to find interior angles?
there is no fix formula for this..........you have to check that what is given to you in the question. According to the given you have to find the interior angle.
How many sides does an angle have?
An angle must have 2 sides or it is no longer an angle.
What angle has 999 sides?
None. An angle has 2 sides.
The intersection of the two sides of an angle is called the angles?
the intesection of the two sides of an angle is the angle 's?
What are sides of angle called?
two rays make up an angle, so the rays are the sides of the angle.
What rays are of the angle?
They are the sides of an angle.
Angle of incidence is equal to the angle of reflection?
Yes, according to the law of reflection, the angle of incidence is equal to the angle of reflection. This means that when a light ray hits a surface and is reflected, the angle it makes with the surface on both sides is the same.
The common endpoint of the sides of the angle?
point of intersection of the sides of the angle; the vertex
Does an acute angle have equal sides?
The length of the sides has nothing to do with the measure of the angle.
Classification of angles according to sides?
Triangles can be classified either according to their sides or according to their angles. All of each may be of different or the same sizes; any two sides or angles may be of the same size; there may be one distinctive angle. Classification by sides includes equilateral, isosceles, and scalene.
What is the converse of the angle bisector theorem?
If a point is on the bisector of an angle, then it is equidistant from the two sides of the angle-apex
