What else can I help you with?
What shape has 3 sides a pair of equal sides and no rational symmetry?
The shape you're describing is an isosceles triangle. It has three sides, with two sides being equal in length, and the third side being different. An isosceles triangle typically does not have rational symmetry, as its symmetry is limited to a single axis of reflection through the vertex opposite the base.
What shape has one line of symmetry but rational symmetry of order none?
triangle
Is a quarter moon shape rational symmetry?
yes
What shape has one line of reflection symmetry and no rotation symmetry?
The letter T for example
Is the parallelograms the reflection symmetry?
A parallelogram normally has no lines of symmetry unless it is in the shape of a rectangle which will then give it 2 lines of symmetry

How many have reflection and rotational symmetry?
It depends on the shape!

Why linear symmetry is called reflection symmetry?
Because linear symmetry defines a line such that the shape is unchanged when REFLECTED in that line.
Is the parallelograms the reflection symmetry?
A parallelogram normally has no lines of symmetry unless it is in the shape of a rectangle which will then give it 2 lines of symmetry
What shape has reflection symmetry but not rotations?
There are many. An isosceles triangle, for example.
Is square s rational symmetry?
is a square a rational symmetry? is a square a rational symmetry?
Does a regular pentagon have rational symmetry?
A regular pentagon has rotational symmetry but does not have rational symmetry. Rational symmetry refers to the property of a shape that can be divided into equal parts by rotations that are fractions of a full rotation (e.g., 1/2, 1/3). Since a regular pentagon can only be rotated by 72 degrees (1/5 of a full rotation) to map onto itself, it does not exhibit rational symmetry.
Is reflection and line symmetry the same thing?
No. You can reflect any shape about a line but if the resulting image is not the same as the original, that line is not a line of symmetry.
What is reflectional summetry?
Reflection symmetry, reflectional symmetry, line symmetry, mirror symmetry, mirror-image symmetry, or bilateral symmetry is symmetry with respect to reflection
