How do you sketch a figure with rotational symmetry but no line symmetry?

When a shape is rotated about its centre, if it comes to rest in a position and looks exactly like the original, then it has rotational symmetry. A shape like an equilateral triangle would therefore have an order of rotational symmetry of 3. The general rule for a regular polygon (shapes such as pentagons, heptagons, octagons etc. is, that the number of sides is the same as the number of lines of symmetry, which is also the same as the rotational symmetry order). This means that a regular hexagon has 6 sides, 6 lines of symmetry and an order of rotational symmetry of 6. Following from this, then a square, which is a regular polygon, has 4 sides, 4 lines of symmetry and an order of rotational symmetry of 4. If a shape has rotational symmetry, it must have either line symmetry or point symmetry or both. For example, a five pointed star has 5 lines of symmetry and rotational symmetry of order 5, but does not have point symmetry. A parallelogram has no line of symmetry, but has rotational symmetry of order 2 and also point symmetry. Only a shape which has line symmetry or point symmetry can have rotational symmetry. When there is point symmetry and also rotational symmetry, the order of the latter is even. For example, the letter 'S' has rotational symmetry of order 2, the regular hexagon of order 6. On this basis, we would suggest that the letter 'F' does not have a rotational symmetry order as it does not have either line symmetry or point symmetry. It doesn't have a centre around which you could rotate it. Sounds weird, but given the definitions, we think this is the case.

What are the types of symmetry on a flat plane?

Rotational symmetry, such as rotating an n-sided regular polygon through angles of 360k/n degrees (2kPI/n radians) about the centre (k is an integer) Reflectional symmetry, where each point perpendicular to a given axis of symmetry at a distance D say, is reflected to the other side of the axis at the point again a distance D from the axis. Translational symmetry. The best examples of such symmetries are sine or cosine curves which are translated a distance 360k degrees (2PI radians) along the x-axis. Tiling patterns are other examples All other types of symmetries in the plane are compositions of the above three.


How could you use symmetry to find side lengths and angle measures of a geometric figure?

The answer will depend on the figure, the type(s) of symmetry and what information about is is given.


What does symmetry balance mean?

Symmetry balance occurs when both sides of a given arrangement are equal. The object is in balance and the same number of items are on each side.


The language with most alphabets is?

Generally speaking, no language uses more than 1 alphabet at any given time in its history. Rare exceptions occur where there are political divisions, such as Serbo-Croatian (which is the same language written with 2 different alphabets).

What is the name of the slow slide of soil and debris downhill in the shape of a spoon?

A rotational landslide (or just rotational slide) is the term usually given to what the USGS calls "A landslide on which the surface of rupture is curved upward (spoon-shaped) and the slide movement is more or less rotational about an axis that is parallel to the contour of the slope."
