A regular 3-d figure formed from pentagons is a dodecahedron (12 faces). However, a soccer ball is not a 3-d shape formed from only regular pentagon. Instead it comprises 12 regular pentagons (usually black) and 20 regular hexagons (white).
The 3-d figure formed from regular pentagons is the dodecahedron which has 20 vertices.
The 3D shape formed by regular pentagons is a dodecahedron, which has 30 edges.
A dodecahedron is a 3-d shape with 12 faces that are regular pentagons.
Tessellation is covering a 2-d surface. Tessellation and making a 3-d shape are not compatible processes. 12 regular pentagons will form a dodecahedron.
In geometry, "regular" means all the sides are the same (and all angles the same). A regular pentagon has all 5 sides the same. Some pentagons have every side different; other irregular pentagons have 2, 3, 4, or 5 sides the same.
hexagons work because each angle is 120 degress, as you say, and 3 times 120 equals 360 degrees. So three hexagons will surround a point with no 'space" left over. but the interior angle of a pentagon is108 degrees. three pentagons together only fill up 3 time 108, or 324 degrees. There is space left over. But four pentagons would overlap. so 3 is not enough and 4 is too many. Pentagons cannot surround a point the way hexagons do.
To text a heart put < and 3 together like <3
There are 5*4*3*2*1 = 120 possibilities.
Regular polygons with 3, 4 or 6 sides.
if you put 3 triangles together you get a bigger triangle.
