What is a Hexagon? - Geometry Made Easy
Quatr.us answers questions



A hexagon is a flat shape, all in one plane, with six sides all of equal length. Each of the six angles measures 120 degrees, so the total interior angles of a hexagon measure 720 degrees (120 multiplied by 6). The hexagon can be cut into six equilateral triangles, all the same size.

The perimeter of a hexagon is the sum of the lengths of all the sides. All the sides are the same length, so that's the same as the length of one side multiplied by six.

The area of a hexagon is the same as the areas of all six equilateral triangles added together (or one equilateral triangle multiplied by six).

One place that hexagons occur in nature is in water ice: the molecules of water (two hydrogen atoms and one oxygen atom) always freeze together in the shape of hexagons.

For the US election, check out Quatr.us' page on the Constitution. From the Revolution on, people have fought for the right to vote. In the 1800s, Andrew Jackson got poor white men the vote; the Civil War and Lincoln brought the vote to African-American men. In the 1900s, women got the vote, and Martin Luther King Jr. fought to force white people to actually let black people vote.
