Does the number 3 have rotational symmetry?
The equilateral triangle will match three times in rotating (turning) around its center. So it has rotational symmetry of Order 3.
Is a line of symmetry and rotational symmetry same?
Rotational symmetry happens when you can spin an image around a point, and it retains symmetry. This is different from the line symmetry we discussed earlier, as that symmetry did not involve moving the image. Rotational symmetry, on the other hand, requires it.
What is rotational symmetry Order 3?
A shape has Rotational Symmetry when it still looks the same after some rotation. As we rotate this image we find three different positions that each look the same. So it has Rotational Symmetry of Order 3.
What shape has exactly 3 lines of symmetry?
equilateral triangle
An equilateral triangle has three lines of symmetry. It has rotational symmetry of order 3. It has three equal sides.
What type of symmetry does the number 3 have?
3 has one horizontal line of symmetry if we draw the top and bottom both equal size.
Which of the following figure have an order of rotation of 3?
Answer:
| Shape | Centre of Rotation | Order of Rotation |
|---|---|---|
| Rhombus | Intersection point of diagonals | 2 |
| Equilateral Triangle | Intersection point of medians | 3 |
| Regular Hexagon | Intersection point of diagonals | 6 |
| Circle | Centre | Infinite |
What is line symmetry?
The line of symmetry can be defined as the axis or imaginary line that passes through the center of the shape or object and divides it into identical halves.
Do all triangles have 3 lines of symmetry?
A scalene triangle is a triangle with no lines of symmetry while an isosceles triangle has at least one line of symmetry and an equilateral triangle has three lines of symmetry.
