## Do all quadrilaterals have 1 lines of symmetry?

A quadrilateral is a 2D shape with four sides. Different types of quadrilateral have different numbers of lines of symmetry.

**Which shape has only one line of symmetry?**

A semicircle has 1 line of symmetry.

### Which quadrilateral has exactly 1 line of symmetry and 1 pair of parallel lines?

trapezoid

Quadrilateral with one pair of parallel sides is a trapezoid. If it has two pairs of parallel sides it is a parallelogram, but parallelograms are also trapezoids.

**Do some Quadrilaterals have no lines of symmetry?**

One type of quadrilateral that has no lines of symmetry is a parallelogram. Parallelograms have four sides and each pair of opposite sides are…

#### Does a trapezoid have one line of symmetry?

The trapezoid has only a vertical line of symmetry. The parallelogram has no lines of symmetry and, as with the rectangle, students should experiment with folding a copy to see what happens with the lines through the diagonals as well as horizontal and vertical lines.

**Does a rhombus have one line of symmetry?**

A rhombus has two lines of symmetry. In a rhombus, the lines of symmetry refer to the lines which divide a rhombus into two identical halves and each half is the mirror image of the other.

## Which triangle has 1 line of symmetry?

isosceles triangle

An isosceles triangle has one line of symmetry. It has rotational symmetry of order 1.

**Does a parallelogram have one line of symmetry?**

The parallelogram has no lines of symmetry and, as with the rectangle, students should experiment with folding a copy to see what happens with the lines through the diagonals as well as horizontal and vertical lines.

### What quadrilateral has 1 pair of parallel sides?

Solution. A trapezoid is a quadrilateral with one pair of opposite sides parallel.

**What is the line of symmetry of a rhombus?**

2Rhombus / Line of symmetry

#### Does a square have one line of symmetry?

A square has 4 lines of symmetry. A horizontal line through the midpoints of the two vertical sides.
