Does every polygon with at least 2 sides of equal length have rotational symmetry?
Yes
A right-angled triangle may have 2 equal sides but only exhibits 1-fold rotational symmetry (ie it is not rotationally symmetric).
However, I believe that any polygon in which each side is parallel to the opposing side must be at least 2-fold rotationally symmetric (ie it is rotationally symmetric).
What else can I help you with?
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.
What are facts about a rhombus?
A rhombus is a polygon. A rhombus is a 4 sided shape and an 'equilateral quadrilateral' (all sides are the same length). Opposite angles are equal in a rhombus. A rhombus can tessellate. A rhombus has two lines of symmetry, joining its opposite corners. A rhombus also has rotational symmetry. A kite is a rhombus, and has rotational symmetry of both 180 degrees as well as 360 degrees, A rhombus is not a regular polygon as all angles have to be congruent for it to be classed as regular.
Does a isosceles trapezoid have rotational symmetry?
Yes, an isosceles trapezoid does have rotational symmetry. An isosceles trapezoid is a quadrilateral with two parallel sides of equal length, which means it can be rotated around its center by certain angles (180 degrees, in this case) and still look the same. This is an example of rotational symmetry, where the shape can be rotated and still appear unchanged.
A polygon with equal sides?
A regular polygon has equal sides in length and angles.
Does a trapezoid have rotational symmetry?
A trapezoid does not have rotational symmetry. Rotational symmetry occurs when a shape can be rotated by a certain angle and still appear the same. In a trapezoid, the angles and side lengths are not equal, so rotating it will result in a different shape. Therefore, a trapezoid does not have rotational symmetry.
Does the pentagon have rotational symmetry?
It depends on the length of the sides, if they are all equal in length, then yes. If not, then the probability of it having rotational symmertry is as likely as not.
Does a kite have rotational syemetry?
Yes, a kite has rotational symmetry. Specifically, it has rotational symmetry of order 1, meaning it can be rotated 180 degrees around its center and still look the same. The two pairs of adjacent sides are equal in length, which contributes to this symmetry. However, it does not have symmetry at any other angle.
What regular polygon that has an order of rotational symmetry of 5?
A regular polygon with an order of rotational symmetry of 5 is a regular pentagon. This means that the pentagon can be rotated by multiples of 72 degrees (360 degrees divided by 5) and still look the same. Each of its five sides and angles is equal, contributing to this symmetrical property.
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.
Which shape has rotational symmetry?
There are many shapes: Any regular polygon. An irregular polygon with an even number of sides in which the opposite sides and angles are equal. An irregular polygon with 3n sides where every third side is equal and every third angle is equal. and so on. A circle, ellipse, disc, oval
Do all figures with rotational symmetry also have reflection symmetry?
No.For example, a hexagon with equal angles and sides of lengths a,b,a,b,a,b has rotational symmetry of order 3, but it has no reflection symmetry.No.For example, a hexagon with equal angles and sides of lengths a,b,a,b,a,b has rotational symmetry of order 3, but it has no reflection symmetry.No.For example, a hexagon with equal angles and sides of lengths a,b,a,b,a,b has rotational symmetry of order 3, but it has no reflection symmetry.No.For example, a hexagon with equal angles and sides of lengths a,b,a,b,a,b has rotational symmetry of order 3, but it has no reflection symmetry.

What are the properties of a regular polygon?
A regular polygon has several properties: All sides are equal in length. All angles are equal in measure. The sum of the interior angles is (n-2)180 degrees, where n is the number of sides. The sum of the exterior angles is 360 degrees. The diagonals, which are line segments connecting non-adjacent vertices, are congruent in length. The polygon has rotational symmetry, which means it can be rotated by a certain angle around its center to coincide with its original position.
Does a kite have reflection symmetry?
Yes, a kite has reflection symmetry. It has one line of symmetry that runs vertically through its center, dividing it into two mirror-image halves. The two pairs of adjacent sides are of equal length, which contributes to this symmetry. However, it does not have rotational symmetry.
What is a polygon with sides of equal length and angles equal mesures called?
A polygon with sides of equal length and equal angles is termed a regular polygon.
How many orders of rotational symmetry does an equilateral triangle have?
3- If an equilateral triangle has 3 equal sides, it also has 3 orders of rotational symmetry.
