What is an example of an object that has symmetry?

In general usage, symmetry most often refers to mirror or reflective symmetry; that is, a line (in 2-D) or plane (in 3-D) can be drawn through an object such that the two halves are mirror images of each other. An isosceles triangle and a human face are examples.

What is a 1/2 Turn symmetry?

So, the 1/2 turn becomes 1/2 of 360° = 180°, and the 1/3 turn becomes 1/3 of 360° = 120°. Then we say the shape on the left has 180° rotational symmetry, and the shape on the right has 120° rotational symmetry. The most common kind of rotational symmetry is half-turn symmetry.

Can a shape have more than one line of symmetry?

In an Asymmetrical figure, none of the sides of the shape is equal. You cannot fold the heart further to get the perfect symmetry. Hence, we can say that the heart-shape has one and only one line of Symmetry. There are some figures wherein the lines of symmetry can be more than one.

Which is the best example of Line symmetry?

One more good example is to imagine if we cut an equilateral triangle into two equal halves, then the two triangles formed after the intersection is the right-angled triangles. Few more examples such as square, rectangle, circle, can also be considered for line symmetry.

How many types of symmetry are there in the world?

Symmetry has many types such as: no line of symmetry, infinite lines of symmetry, 1 and 2 lines of symmetry in detail. There are many shapes which are irregular and cannot be divided into equal parts. Such shapes are termed as asymmetrical shapes. Hence, for such cases, line symmetry is not applicable.

When is a crease a line of symmetry?

If the figure can be folded along a straight line so that one half of the figure exactly matches the other half, the figure has line symmetry. The crease is the line of symmetry. Place your shape against the original figure to check that each crease is a line of symmetry.
