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
No angle has 10 sides. An angle has two sides.
An angle must have 2 sides or it is no longer an angle.
If one angle is a right angle, it is a right triangle. If one angle is an obtuse angle, it is an obtuse triangle. If there are no right nor obtuse angle then it is an acute triangle.
Exterior Angle = 360/number of sides. Interior Angle = 180 - Exterior Angle. Combining Interior Angle = 180 - (360/number of sides).
None. An angle has 2 sides.
the intesection of the two sides of an angle is the angle 's?
two rays make up an angle, so the rays are the sides of the angle.
They are the sides of an angle.
point of intersection of the sides of the angle; the vertex
The length of the sides has nothing to do with the measure of the angle.
If a point is on the bisector of an angle, then it is equidistant from the two sides of the angle-apex
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.
