A regular hexagon is a polygon with 6 sides of equal measure. For all regular polygons, the number of lines of symmetry is equal to the number of sides. About Us. Already booked a tutor? Learn Math Questions with tutors mapped to your child's learning needs.

Lines of symmetry hexagon

A regular hexagon is defined as a hexagon that is both equilateral and equiangular. It is bicentric , meaning that it is both cyclic has a circumscribed circle and tangential has an inscribed circle. All internal angles are degrees. A regular hexagon has six rotational symmetries rotational symmetry of order six and six reflection symmetries six lines of symmetry , making up the dihedral group D 6. The longest diagonals of a regular hexagon, connecting diametrically opposite vertices, are twice the length of one side. From this it can be seen that a triangle with a vertex at the center of the regular hexagon and sharing one side with the hexagon is equilateral , and that the regular hexagon can be partitioned into six equilateral triangles. Like squares and equilateral triangles , regular hexagons fit together without any gaps to tile the plane three hexagons meeting at every vertex , and so are useful for constructing tessellations. The cells of a beehive honeycomb are hexagonal for this reason and because the shape makes efficient use of space and building materials. The Voronoi diagram of a regular triangular lattice is the honeycomb tessellation of hexagons. It is not usually considered a triambus , although it is equilateral. The maximal diameter which corresponds to the long diagonal of the hexagon , D , is twice the maximal radius or circumradius , R , which equals the side length, t. The minimal diameter or the diameter of the inscribed circle separation of parallel sides, flat-to-flat distance, short diagonal or height when resting on a flat base , d , is twice the minimal radius or inradius , r. The maxima and minima are related by the same factor:. For any regular polygon , the area can also be expressed in terms of the apothem a and the perimeter p.

When the side length AB is given, drawing a circular arc from point A and point B gives the intersection M, the center of the circumscribed circle. They have line symmetry and rotational symmetry.

In geometry, a hexagon can be defined as a closed two-dimensional polygon with six sides. Hexagon has 6 vertices and 6 angles also. We can find the shape of a hexagon in a honeycomb, a football, face of pencil, and floor tiles. Hexagonal shape is classified into several types based on the measure of sides and angles. When the length of all the sides and measure of all the angles are equal, it is a regular hexagon.

The shape will look the same on both sides of the line of symmetry. We can mark lines of symmetry using a dashed line drawn on the shape. We can find lines of symmetry using a mirror. We have a line of symmetry if the reflection of the shape in the mirror looks the same as the shape in front of the mirror. A line of symmetry can be found by folding the shape. If the shape can be folded in half, the line of the fold is a line of symmetry. We fold the shape over and if one half lies exactly on top of the other half, we have a line of symmetry. Lines of symmetry are lines that divide shapes in half. Both sides of the line of symmetry look exactly the same.

Lines of symmetry hexagon

A line of symmetry is a line that divides a figure into two identical parts. The figure below shows 3 line of symmetry examples. A line of symmetry is defined as an imaginary line that divides an object into two identical symmetrical halves. Another way to think about this is: if a figure can be folded over a line such that each half perfectly overlaps, the line is a line of symmetry.

A regular hexagon can be dissected into six equilateral triangles by adding a center point. There are no other lines that can be drawn that divides the photo into two equal halves that are mirror images of each other. The equilateral triangle has 3 lines of symmetry. For any regular polygon , the area can also be expressed in terms of the apothem a and the perimeter p. There are other symmetry polyhedra with stretched or flattened hexagons, like these Goldberg polyhedron G 2,0 :. Lines of symmetry in regular shapes Regular polygons are polygons that have equal side lengths and equal angle measures. Example 1: Find the perimeter of a regular hexagon having each side measure 20 cm. Irregular hexagons with parallel opposite edges are called parallelogons and can also tile the plane by translation. It follows from the ratio of circumradius to inradius that the height-to-width ratio of a regular hexagon is The maximal diameter which corresponds to the long diagonal of the hexagon , D , is twice the maximal radius or circumradius , R , which equals the side length, t. Lines of symmetry FAQs. The 12 roots of the Exceptional Lie group G2 , represented by a Dynkin diagram are also in a hexagonal pattern. A regular hexagon can be stellated with equilateral triangles on its edges, creating a hexagram. Easy mistakes to make Not visualizing that a line of symmetry is like a fold line For example, thinking that this is a line of symmetry.
