# Question: Has At Least One Line Of Symmetry?

## Which is not a line of symmetry?

Not all lines that divide a figure into two congruent halves are lines of symmetry.

The diagonal of a rectangle divides the rectangle into two triangles that are congruent (same size and shape).

But the diagonal line is NOT a line of symmetry.

Folding along the diagonal does not coincide with the other side..

## Does a parallelogram have at least one line of symmetry?

1 Answer. General parallelogram has no lines of symmetry. Some specific types of parallelogram do. See below.

## Which of the given figures have at least one line of symmetry?

Answer. Answer: Each regular polygon (equilateral triangle, square, rhombus, regular pentagon, regular hexagon etc.)

## Is a rhombus symmetrical?

A rhombus has an axis of symmetry through each pair of opposite vertex angles, while a rectangle has an axis of symmetry through each pair of opposite sides. The diagonals of a rhombus intersect at equal angles, while the diagonals of a rectangle are equal in length.

## What is an example of a line of symmetry?

Each regular polygon (equilateral triangle, square, rhombus, regular pentagon, regular hexagon etc.) are symmetry. The number of lines of symmetry in a regular polygon is equal to the number of sides a regular polygon has. Some figures like scalene triangle and parallelogram have no lines of symmetry.

## What is the meaning of line of symmetry?

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. A square has 4 lines of symmetry, as shown below.

## What is axis symmetry?

The axis of symmetry of a parabola is a line about which the parabola is symmetrical. When the parabola is vertical, the line of symmetry is vertical. When a quadratic function is graphed in the coordinate plane, the resulting parabola and corresponding axis of symmetry are vertical. Algebra. STANDARD FORM.

## 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.

## Which letter has only one line of symmetry?

The letter Z has one line of symmetry.

## Which letters of the alphabet have lines of symmetry?

What Lines of Symmetry Are Found in Alphabet Letters? In standard fonts, the letters A, M, T, U, V, W and Y each has a vertical line of symmetry that divides it into two corresponding mirror images. B, C, D, E and K have horizontal lines of symmetry.

## What are the 4 types of symmetry?

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

## What Quadrilaterals have no lines of symmetry?

Parallelogram. A parallelogram is a quadrilateral with no axis of line symmetry. The opposite sides of a parallelogram are equal and parallel. The opposite angles of a parallelogram are equal.

## How do I find the line of symmetry?

To find the line of symmetry algebraically, you need to identify if the equation is written in standard form or vertex form. Standard form is y = ax^2 + bx + c, where a, b, and c equal all real numbers. You can use the formula x = -b / 2a to find the line of symmetry.

## Which letter has 2 lines of symmetry?

Letter H,I and X has two line of symmetry.

## Do all quadrilaterals have 2 lines of symmetry?

So the square has four lines of symmetry. The rectangle has only two, as it can be folded in half horizontally or vertically: students should be encouraged to try to fold the rectangle in half diagonally to see why this does not work. The trapezoid has only a vertical line of symmetry.
