The primary classification of a polygon is according to the number of sides (or vertices) that it has.If all the sides are of equal length and all the angles are of the same measure then it is a regular polygon.If any of the angles is a reflex angle then it is a concave polygon, otherwise it is convex.
Classification of triangles by their sides:equilateral = 3 sides are equalisosceles = 2 sides are equalscalene =no equal sideClassification of triangles by their angles:acute = the 3 angles are less less than 90 degreesright = it has an angle which is 90 degreesobtuse = it has an angle which is more than 90 degrees
A right angle because it complies with Pythagoras' theorem.
Degrees
Triangle: 3 sides Quadrilateral: 4 sides Pentagon: 5 sides Hexagon: 6 sides Heptagon: 7 sides Octagon: 8 sides Nonagon: 9 sides Decagon: 10 sides And there are many more
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.
Classification of triangles according to sides: -Scalene Triangle - a triangle with no 2 congruent sides. -Isosceles Triangle - a triangle with at least 2 congruent sides. -Equilateral Triangle - a triangle with 3 congruent sides. Classification of triangles according to angles: -acute triangle - a triangle with 3 acute angles. -right triangle - a triangle with one right angle. -equiangular triangle - a triangle with 3 congruent angles. -obtuse triangle - a triangle with one obtuse angle.
equilateral= all sides are the same length isosceles = two sides are the same, one is different

No angle has 10 sides. An angle has two sides.
A triangle can be classified according to its sides or the magnitude of its largest angle (two of the angles MUST be acute angles). All three sides equal: equilateral. Such a triangle must be equiangular, but that term is rarely used. Two equal angles, third one different (or two sides equal and third different): isosceles. All three angles different (all three sides different): scalene. Largest angle = 90 degrees: A right angled triangle. Largest angle obtuse: An obtuse angled triangle.

A right angle because it complies with Pythagoras' theorem.
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).
An angle must have 2 sides or it is no longer an angle.
Equilateral: All angles of a triangle are 60 degrees, they are all equal. Right: One angle is 90 degrees (right angle), the other 2 are acute. Acute: All three angle are acute (less than 90 degrees). Obtuse: One obtuse (greater than 90 degrees) angle. Isosceles: Two sides of equal lenght, 2 equal angles. Scalene: No sides of equal length, angles are all different in size.
