## What does an object have if both sides match exactly when folded or divided?

When a figure is folded in half, along its line of symmetry, both the halves match each other exactly. This line of symmetry is called the axis of symmetry.

### When you can fold a figure on a line and the two halves match perfectly?

If a figure can be folded or divided into half so that the two halves match exactly then such a figure is called a symmetric figure.

**Which shape can be folded into two equal halves?**

E.g. – A rectangle: As shown above, the rectangle can be divided into two equal halves either along the vertical line or along the horizontal line. Hence, a rectangle is said to have two axis of reflection symmetry.

**What is line symmetry in a shape?**

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 is an asymmetrical shape?

1 : having two sides or halves that are not the same : not symmetrical an asymmetrical design asymmetrical shapes.

### How do we know if the shape is symmetrical or asymmetrical?

The images which can be divided into identical halves are called symmetrical. The images that cannot be divided into identical halves are asymmetrical.

**What is asymmetrical shape?**

Something asymmetrical has two sides that don’t match — it’s uneven or out of whack. Asymmetrical things are irregular and crooked, and don’t match up perfectly when folded in half. Drawing something perfectly symmetrical is pretty hard, so most of your creations are probably asymmetrical.

**What is symmetry and its types?**

Mathematically, symmetry means that one shape becomes exactly like another when you move it in some way: turn, flip or slide. There are three basic types of symmetry: rotational symmetry, reflection symmetry, and point symmetry.

## What fraction is two halves?

A half is 1/2 of the whole. 1/2 is 1 out of 2 equal parts. 👉 2 halves make one whole. As Nick is about to cut the pie, two more friends join them.

### Which shape is divided into halves?

One way to divide a rectangle into halves is this way. What have we learned in this video? We’ve learned that when we divide shapes into two equal parts, we call each part a half.

**What are 2 lines of symmetry?**

Two Lines of Symmetry can be a combination of Vertical, diagonal or Horizontal Lines. Letters such as H and X also have two lines of Symmetry. An hourglass is also an example of Two Lines of Symmetry. A rectangle does not have a diagonal line of symmetry as opposed to square as its sides are not the same.

**What is the shape of horizontal line?**

A horizontal line is a straight line that is drawn from left to right or right to left and it is parallel to the x-axis in the coordinate plane. In other words, a straight line that has an intercept only on the y-axis, not on the x-axis is called a horizontal line.

## What is symmetry of 2D shapes?

Symmetry of 2-D Shapes. A 2-D figure has line symmetry when it can be divided or folded so that the two parts match exactly. The fold line is called the line of symmetry. Any given line of symmetry divides a figure into equal halves. It may also be said that each of the halves are mirror images of each other.

### How do you find the line of symmetry by folding?

Folding Test. You can find if a shape has a Line of Symmetry by folding it. When the folded part sits perfectly on top (all edges matching), then the fold line is a Line of Symmetry.

**When does a 2-D figure have line symmetry?**

A 2-D figure has line symmetry when it can be divided or folded so that the two parts match exactly. The fold line is called the line of symmetry. Any given line of symmetry divides a figure into equal halves.

**How many lines of symmetry does a shape have?**

Shapes may have multiple lines of symmetry and the lines of symmetry can be vertical, horizontal, or diagonal. The more sides that a regular polygon has, the greater the number of lines of symmetry there are. A circle has an infinite number of lines of symmetry. In this video, we find lines of symmetry in a 2D shape.
