To this point, the regular pentagon is rotationally symmetric at a rotation of 72° or multiples of this. . First, to prove a pentagon cannot form a regular tiling (one in which all faces are congruent, thus requiring that all the polygons be pentagons), observe that 360° / 108° = 31⁄3 (where 108° Is the interior angle), which is not a whole number; hence there exists no integer number of pentagons sharing a single vertex and leaving no gaps between them. A pyritohedron has 12 identical pentagonal faces that are not constrained to be regular. Sean Gilmartin Baby, The area of a convex regular pentagon with side length t is given by.

You multiply that area by 5 for the area of the pentagon. From MathWorld--A Wolfram Web Resource. None of the pentagons have any symmetry in general, although some have special cases with mirror symmetry. Let then D be the intersection of lines A D and B D, parallel respectively to B C and A E. Many echinoderms have fivefold radial symmetry. None of the pentagons have any symmetry in general, although some have special cases with mirror symmetry. That means we can carve the pentagon into smaller shapes we can easily find the area of and add (or multiply). Altitude (height) The altitude (or height) of a parallelogram is the perpendicular distance from the base to the opposite side (which may have to be extended).
