How many basic geometric shapes are there?
Geometric shapes formed from three or more straight lines (polygons) include:3 sidestriangle4 sides (quadrilaterals)square (4 equal sides, right angles)trapezoid (4 sides with only 1 set of parallel lines)rectangle (4 sides with 2 sets of parallel lines)rhombus (4 sides, 2 parallel pair)5 sides - pentagon6 sides - hexagon7 sides - heptagon (rarely septagon)8 sides - octagon9 sides - enneagon (classically - nonagon)10 sides - decagon11 sides - hendecagon (classically - undecagon)12 sides - dodecagon (classically - duodecagon)13 sides - tridecagon or triskaidecagon14 sides - tetradecagon15 sides - pentadecagon16 sides - hexadecagon17 sides - heptadecagon18 sides - octadecagon19 sides - enneadecagon (nonadecagon)20 sides - icosagon*For a list of some other basic shapes, see the related link.
What has 3 pairs of parallel faces and 8 pairs of perpendicular faces?
a cube * * * * * It cannot be a cube because a cube does not have 8 pairs of perpendicular faces - it has 12.
