##### (viii) Symmetry of a Rectangle:

A rectangle has two lines of symmetry along the line segments joining the mid-points of the opposite sides. EF and GH are two lines of symmetry of rectangle ABCD.

##### Is a rectangle symmetrical?

A rectangle has 2 lines of symmetry which divides it into two identical parts. … A shape can be two or more lines of symmetry. To recall, a rectangle is one of the quadrilaterals whose two opposite sides are equal and parallelogram.

##### (ix) Symmetry of a Square:

A square has four lines of symmetry, two along the line segments joining the mid-points of opposite sides and two along the diagonals. ABCD is a square having PQ, RS, AC and BD as the lines of symmetry.

##### (x) Symmetry of a Kite:

A kite, has one line of symmetry along the diagonal AC.

##### (xi) Symmetry of a Circle:

A circle has an infinite number of lines of symmetry all along the diameters.

##### How many symmetry has a circle?

Since there are an infinite number of lines through the center, the circle has an infinite number of lines of symmetry. When the circle is folded over a line of symmetry, the parts of the circle on each side of the line match up. … So a line of symmetry divides the circle into two parts with equal area.

##### What lines of symmetry does a rectangle have?

A rectangle has 2 lines of symmetry which divides it into two identical parts. A shape can be different types of symmetry, such as linear symmetry, mirror symmetry, reflectional symmetry, and so on. To recall, a rectangle is one of the quadrilaterals whose two opposite sides are equal and parallelogram.

##### Why does a square have 4 lines of symmetry?

For the square, it can be folded in half over either diagonal, the horizontal segment which cuts the square in half, or the vertical segment which cuts the square in half. So the square has four lines of symmetry.

##### Which figure has no line of symmetry?

Parallelogram. A parallelogram has no lines of symmetry.
