 # Question: How Many Symmetry Does A Triangle Have?

## Does a rectangle have reflection symmetry?

A shape has symmetry if it is indistinguishable from its transformed image.

A rectangle is an example of a shape with reflection symmetry.

A line of reflection through the midpoints of opposite sides will always be a line of symmetry.

A rectangle has two lines of symmetry..

## How many symmetry does a rectangle have?

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.

## What is the name for the longest side of a right angled triangle?

hypotenuseThe hypotenuse of a right triangle is always the side opposite the right angle. It is the longest side in a right triangle. The other two sides are called the opposite and adjacent sides.

## How many symmetry are there?

Regular PolygonsAn Equilateral Triangle (3 sides) has 3 Lines of SymmetryA Square (4 sides) has 4 Lines of SymmetryA Regular Pentagon (5 sides) has 5 Lines of SymmetryA Regular Hexagon (6 sides) has 6 Lines of SymmetryA Regular Heptagon (7 sides) has 7 Lines of Symmetry1 more row

## Is there a triangle with 2 lines of symmetry?

No triangle has 2 lines of symmetry. Equilateral triangle has three lines of symmetry while an isosceles has one. A scalene triangle has none.

## What is symmetry of triangle?

What is a Symmetrical Triangle. A symmetrical triangle is a chart pattern characterized by two converging trend lines connecting a series of sequential peaks and troughs. These trend lines should be converging at a roughly equal slope.

## What types of triangles have rotational symmetry?

We find that the equilateral triangle has three lines of symmetry, the isosceles triangle has one line, and the scalene triangle has none. With respect to rotation symmetry, only the equilateral triangle has rotation symmetry.

## Do triangles have symmetry?

But the diagonal line is NOT a line of symmetry. When folding along the diagonal, the two halves (triangles) do not coincide. … Basically, a figure has point symmetry when it looks the same when up-side-down, (rotated 180º), as it does right-side-up.

## What is symmetry and its types?

Objects are said to be symmetrical if their pre-image and image have the same size and shape, but are either mirror images of each other or one has been rotated to go in a different direction from the first. There are three basic types of symmetry: reflection symmetry, rotational symmetry, and point symmetry.

## How many symmetry lines does a triangle have?

The division of triangles into scalene, isosceles, and equilateral can be thought of in terms of lines of symmetry. A scalene triangle is a triangle with no lines of symmetry while an isosceles triangle has at least one line of symmetry and an equilateral triangle has three lines of symmetry.

## Is 3 a symmetrical number?

0, 3, 8 are the numbers which have lines of symmetry. A line of symmetry is a line that divides the given shape into identical parts. 0 and 8 have two lines of symmetry. 3 have one line of symmetry. Remaining numbers do not have any lines of symmetry.

## What is a symmetrical shape?

A 2D shape is symmetrical if a line can be drawn through it and either side is a reflection of the other. … This is sometimes called a ‘mirror line’ or ‘mirror symmetry’, because if you put a mirror on the line, the reflection would show the whole shape. • An isosceles triangle has 1 line of symmetry.

## What shape has no line of symmetry?

Two shapes that have no lines of symmetry are the scalene triangle and an irregular quadrilateral.

## What triangle has no lines of symmetry but has 180 rotation?

What quadrilateral has no lines of symmetry but has 180 degree rotation symmetry? Parallelogram. A parallelogram is a quadrilateral with no axis of line symmetry. The opposite sides of a parallelogram are equal and parallel.

## Does a triangle have 3 lines of symmetry?

An equilateral triangle has three lines of symmetry. It has rotational symmetry of order 3. It has three equal sides.

## What are the 4 types of symmetry?

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

## Is the number 8 symmetrical?

8 has two lines of symmetry and 180 degree rotational symmetry if you draw the top and bottom the same size. If you make the top smaller than the bottom, it has only one vertical line of symmetry.
