A line that reflects a figure onto itself is called a line of symmetry. A figure that can be carried onto itself by a rotation is said to have rotational symmetry. Every four-sided polygon is a quadrilateral.Click to see full answer. Also question is, how many line of symmetry does a quadrilateral have? Quadrilaterals Square (all sides equal, all angles 90°) Rectangle (opposite sides equal, all angles 90°) Irregular Quadrilateral 4 Lines of Symmetry 2 Lines of Symmetry No Lines of Symmetry Likewise, what is a symmetry line? We often find symmetry in things around us. We say there is symmetry when the exact reflection or mirror image of a line, shape or object gets created. The line of symmetry can be defined as the axis or imaginary line that passes through the center of the shape or object and divides it into identical halves. Keeping this in view, what is a quadrilateral with no lines of symmetry? A parallelogram is a quadrilateral with no axis of line symmetry. 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.
