A scalene triangle has one order of rotational symmetry.
If u came here n u've just read dis **** off :D lool im jokin it ac has 2
In the UK, three basic shapes are: Circle gives orders (No Entry, etc). Triangle gives a warning (Road Works Ahead, etc). Rectangle gives information (To a castle, or tourist destination, etc).
It can have orders 1 and 7.
Permutation
A PO represents an obligation of funds in GFEBS
3- If an equilateral triangle has 3 equal sides, it also has 3 orders of rotational symmetry.
The rectangle's rotational symmetry is of order 2. A square's rotational symmetry is of order 4; the triangle has a symmetry of order 3. Rotational symmetry is the number of times a figure can be rotated and still look the same as the original figure.
If it's a regular 8 sided octagon then it rotational symmetry to the order of 8
7
A parallelogram.
A star typically has rotational symmetry depending on its number of points. For example, a five-pointed star has five orders of rotational symmetry, meaning it looks the same after a rotation of 72 degrees (360 degrees divided by 5). The number of orders of rotational symmetry is equal to the number of points on the star.
Because the circle's diameter has infinite lines of symmetry
It need not have any rotational symmetry or it can have 5.
It have 4 axis of symmetry . Two Perpendiculars and two Diagonals
Four, if the quadrilateral is a square, but if it is a rectangle it only has two and if it is an irregular quadrilateral it most probably only has one. So a rectangle, a rhombus, and a parallelogram have two, orders of rotational symetry but a kite and a trapezium although quadrilaterals (4sides) only have one.
An order of symmetry is the number of times a line of symmetry can be drawn through a shape. For example, a square has four orders of symmetry: One up and down, one left and right, and two diagonal. A rectangle has an two orders of symmetry. A circle has an infinite number of orders of symmetry.
