Any polygon with 3n sides (n > 1) where every nth side is equal and every nth angle is equal: that is the sides and angles repeat in sets of n.

For example a hexagon (n = 2) with

sides of length x,y,x,y,x,y

and

angles of P,Q,P,Q,P,Q.

What is a shape with rotational order of 3 and 0 lines of symmetry?

Triangle * * * * * The only triangle with rotational symmetry of order 3 is an equilateral triangle and that has 3 lines of symmetry, not 0. The triskelion (the three legs) on the Isle of Man flag has rotational symmetry of order 3 but no lines of symmetry.


Show you a shape with 3 lines of symmetry and rotational symmetry with order 3?

An equilateral triangle.


A polygon with Rotational symmetry order of 3 is?

A shape like an equilateral triangle would therefore have an order of rotational symmetry of 3


What shape has 3 lines of symmetry and a rotational order of 3?

An equilateral triangle.


What is the shape with no lines of symmetry and rotational symmetry with order of 3?

Scalene triangle * * * * * A scalene triangle does not have rotational symmetry of order 3. The triskelion (the three legs) on the Isle of Man flag, or a simplified version of that shape will meet the requirements.


How much rotational symmetry does triangle have?

It depends on the type of triangle. A scalene triangle (no equal sides) has no rotational symmetry. An isosceles triangle (2 equal sides) has rotational symmetry order 2. An equilateral triangle (3 equal sides) has rotational symmetry order 3. The order of rotational symmetry is how many time a shape will fit over itself during one complete rotation.
