A hexagon has six perpendicular lines. Perpendicular lines are lines that intersect at a 90-degree angle.
The sum of the internal angles of a hexagon is 540 degrees. This means that all six sides can be divided into three equal parts, each 120 degrees long; or two equal parts, each 240 degrees long. Each line divides the hexagon into two triangles, with the vertex angles adding up to 540 degrees. The line that runs through the center of the hexagon does not divide it into triangles, but it does divide it into quadrilaterals — four-sided figures with two pairs of opposite sides parallel to each other and four right angles between them.
In addition to dividing the hexagon into triangles and quadrilaterals, its six sides also divide it into two sets of three identical triangles each. Each set has an angle of 120 degrees between them, so they add up to 240 degrees total.
