What shapes have no lines of symmetry?

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

What is not a line of symmetry in a triangle?

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.

Which polygon does not have a line of 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 right angle have a line of symmetry?

A right angled triangle, if it is isosceles right angled triangle then it will have one line of symmetry. if it is equilateral right angled triangle then it will have three lines of symmetry. if it is scalene right angled triangle then it will have no line of symmetry.

How many symmetry lines does a rectangle have?

two lines

What do you call a rectangle that has 4 lines of symmetry?

If a rectangle has four line of symmetry this means that’s the square.

How many symmetry lines does a rhombus have?

How many horizontal lines does a rhombus have?

A rhombus has two lines of symmetry i.e horizontal line of symmetry and vertical line of symmetry. In a rhombus, the line of symmetry divides it into two equal halves and each half of the rhombus is considered as the mirror image of the other. The lines of symmetry of rhombus are drawn from its diagonals.

Does a rhombus have reflection symmetry?

A rhombus has reflectional symmetry over either of its diagonals. Like the parallelogram, it also has rotational symmetry of 180º about its center.

What is the smallest rotational symmetry of a rhombus?

A rhombus has rotational symmetry of 180º (Order 2). sides and 4 right angles. A square has two pairs of parallel sides.

Does a rectangle have reflection symmetry?

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. You can imagine folding the rectangle along each line of symmetry and each half of the rectangle would match up perfectly.

Do parallelograms have reflection symmetry?

And though a parallelogram has a rotational symmetry when rotated at an angle of 1800 about its center, but has no reflection symmetry. Thus, no line can divide the parallelogram in two symmetric shapes.

Why does a rectangle not have 4 lines of symmetry?

A line of symmetry divides a figure in half. A rectangle cannot have a diagonal line of symmetry like a square because the sides are not the same length. If you fold this rectangle diagonally so that Corner A meets Corner D, the sides would not match.

What shape has 2 right angles and 2 angles that are not right angles?


How many right angles are in letter E?

four right
