## Which shape has 2 lines of symmetry?

rectangleA shape can have more than one line of symmetry.

Thus a rectangle has two lines of symmetry, an equilateral triangle has three lines of symmetry, and a square has four.

A circle has an infinite number of lines of symmetry since it can be folded about any diameter..

## What is angle of rotation of circle?

In mathematics, the angle of rotation is a measurement of the amount, of namely angle, that a figure is rotated about a fixed point, often the center of a circle. … If a cart moves around the wheel once, the angle of rotation is 360°.

## How many lines of symmetry does a diamond have?

two linesAnswer and Explanation: If all four of the diamond’s sides are equal, a diamond has two lines of symmetry – horizontal and vertical.

## How many lines of symmetry does a semi circle have?

one lineIn mathematics (and more specifically geometry), a semicircle is a one-dimensional locus of points that forms half of a circle. The full arc of a semicircle always measures 180° (equivalently, π radians, or a half-turn). It has only one line of symmetry (reflection symmetry).

## What is symmetry line in math?

A line of symmetry is a line that cuts a shape exactly in half. This means that if you were to fold the shape along the line, both halves would match exactly. Equally, if you were to place a mirror along the line, the shape would remain unchanged. … An equilateral triangle has 3 lines of symmetry.

## What shape has only 1 line of symmetry?

KiteKite. A kite has one line of symmetry. It has rotational symmetry of order one.

## Which letter has no line of symmetry?

Letters like B and D have a horizontal line of symmetry: their top and bottom parts match. Some letters, for example, X, H, and O, have both vertical and horizontal lines of symmetry. And some, like P, R, and N, have no lines of symmetry.

## Does a circle have a line of symmetry?

A circle has unlimited lines of symmetry!

## What type of symmetry do circles have?

Since a circle has infinitely many diameters, it has infinitely many lines of reflectional symmetry. Furthermore, any size sector in the circle can be rotated about the center point, so this creates infinitely many instances of radial symmetry.

## What are the 3 basic types of symmetry?

Animals can be classified by three types of body plan symmetry: radial symmetry, bilateral symmetry, and asymmetry.

## Is a smiley face symmetrical?

Notice that both sides of the happy face look exactly the same. That means this figure is symmetrical.

## What are the 4 types of symmetry?

The four main types of this symmetry are translation, rotation, reflection, and glide reflection.

## Which shape has two lines of symmetry but no right angles?

ParallelogramParallelogram. A parallelogram has no lines of symmetry. It has rotational symmetry of order two.

## How do you explain symmetry?

What is symmetry? Something is symmetrical when it is the same on both sides. A shape has symmetry if a central dividing line (a mirror line) can be drawn on it, to show that both sides of the shape are exactly the same.
