Definition of pentagon in math
WebA line of symmetry is the line that divides a shape or an object into two equal and symmetrical parts. We also call this line the axis of symmetry or mirror line because it divides the figure symmetrically, and the divided parts look like mirror reflections of each other. More line of symmetry examples are shown in the figure below. WebA 5-sided polygon (a flat shape with straight sides). See: Polygon. Pentagon.
