Q:

How many lines of symmetry does a parallelogram have?

A:

The number of lines of symmetry of a parallelogram depends on the type of parallelogram. A non-special parallelogram does not have any lines of symmetry. This includes any quadrilateral with two pairs of parallel and equal sides, except for rectangles, squares and rhombuses.

A rectangle is a parallelogram with four right angles. This property allows it to have two lines of symmetry.

A rhombus is a parallelogram with four equal sides. The number of lines of symmetry of a rhombus depends on whether it is a square or not. If it has four right angles, the rhombus is a square and thus has four lines of symmetry. If not, the rhombus only has two lines of symmetry.

    How many lines of symmetry are in a circle?

    A:

    Circles have an infinite number of lines of symmetry. Any line that bisects a circle through its center is a line of symmetry. Circles are the only Euclidean shape with this property.

  • Q:

    What is the difference between a parallelogram and a rhombus?

    A:

    The difference between a parallelogram and a rhombus is that a parallelogram is a quadrilateral whose opposite sides are parallel to one another regardless of how many sides the figure has, and a rhombus is a parallelogram that has four sides with two opposites sides that are equal to one another. When all sides of the parallelogram are equal but have angles that are not equal to 90 degrees, it is also called a rhombus.

    What is the perimeter of a parallelogram?

    A:

    The perimeter of a parallelogram, as for any polygon, is the sum of the lengths of its sides. The opposite sides of a parallelogram are parallel and have the same measurement. The formula for its perimeter is twice the sum of the base and the height or "2(b + h)."
