Does an equilateral triangle have any rotational symmetry?
An equilateral triangle has rotational symmetry (order 3).
Do any kinds of triangle have rotational symmetry but no lines of symmetry?
No.
What shape with 3 sides has no lines of symmetry?
Any triangle that is not isosceles or equilateral. An equilateral triangle has 3 lines of symmetry, while an isosceles triangle has only one, and any other triangle (non-isosceles right triangle, or scalene triangle) has zero.
What is the order of rotational symmetry of an isosceles trapezium?
An isosceles trapezium (or isosceles trapezoid) has an order of rotational symmetry of 1. This means it can only be rotated 360 degrees to look the same at one position, as it does not map onto itself at any other angle of rotation. In contrast, shapes with higher rotational symmetry can appear the same at multiple angles.
What type of triangle has only line symmetry and no rotational symmetry of order more than 1?
A scalene triangle has only line symmetry and no rotational symmetry of order more than 1. In a scalene triangle, all sides and angles are different, preventing it from having any rotational symmetry. It may have at most one line of symmetry if it has a specific arrangement or reflection, but generally, it lacks line symmetry entirely.
Does an equilateral triangle have any rotational symmetry?
An equilateral triangle has rotational symmetry (order 3).
What rotational symmetry does a right-angled triangle have?
I think none. In fact the only triangle that I believe has any rotational symmetry is an equilateral triangle.
Do any kinds of triangle have rotational symmetry but no lines of symmetry?
No.
What shape with 3 sides has no lines of symmetry?
Any triangle that is not isosceles or equilateral. An equilateral triangle has 3 lines of symmetry, while an isosceles triangle has only one, and any other triangle (non-isosceles right triangle, or scalene triangle) has zero.
What is the order of rotational symmetry of a 3D triangle?
It need not have any symmetry.
How many lines of symmetry does an obtuse angle isosceles triangle have?
Any isosceles triangle that is not also equilateral has exactly one line of symmetry.
Which shape has 3 sides and 1 line of symmetry?
An isosceles triangle.* * * * *An equilateral triangle has 3 lines of symmetry, while an isosceles triangle has only one, and any other triangle (non-isosceles right triangle, or scalene triangle) has zero.

Which shape has line of symmetry but not rotational symmetry?
There are infinitely many such shapes:Take any odd-sided regular polygonMove one vertex away from the side opposite it in a perpendicular direction any distance you like.The resulting shape has one line of symmetry (from the vertex moved to the centre of the opposite side) and no rotational symmetry.Done to an equilateral triangle (a regular "3-agon") this creates an isosceles triangle.
Has a triangle got 2 lines of symmetry and 2 lines of rotational symmetry?
First of all, your grammar is terrible. The question should be "Does a triangle have 2 lines of symmetry and 2 lines of rotational symmetry? and the answer is no. A triangle can not have 2 lines of rotational symmetry, because you only rotate the image, you do not use any lines.
Does a right triangle have rotational symmetry?
Well, honey, a right triangle does not have rotational symmetry because if you try to rotate it by any angle other than 90 degrees, it won't look the same. So, unless you're planning on spinning that triangle like a disco ball at a 70s party, you won't find any rotational symmetry there.
Triangle with one axis of symmetry?
Any isosceles triangle which is not also an equilateral triangle. An equilateral triangle would have three.
