pentagon
First of all, it's called a pentagon. It's special for many reasons. A pentagon shaped building offers more support than a quadrilateral (four sided shape). Also, the US Dept. of Defense has its headquarters in the Pentagon which is the shape of a pentagon.
A pentagon if all sides are equal - if they are not it is called a polygon
A cube. A 3-D shape with 6 sides which are all squares.
In geometry, a pentagon (from the Greek πέντε pente and γωνία gonia, meaning five and angle) is any five-sided polygon or 5-gon. The sum of the internal angles in a simple pentagon is 540°. A self-intersecting regular pentagon (or star pentagon) is called a pentagram.
No. A regular polygon has all sides the same length and all angles the same size. A regular pentagon has 5 angles each 108 degrees. A house-shaped pentagon does not have all angles the same size, so therefore it cannot be regular.
The Pentagon in Washington is obviously shaped like a pentagon. Black shapes on soccer balls, some road signs and the home plate on a baseball field are all pentagonal shaped objects.
The shape that has 5 sides is called a pentagon, from pent meaning 5 and gon meaning side. If all these sides are the same length, and all angles in the pentagon are equal, it is a regular pentagon. Otherwise, it is an irregular pentagon.
All except the base are always triangles; the shape of the base gives the name to the pyramid; eg a pentagonal pyramid has a pentagon as the base and five triangular faces; a triangular pyramid has three triangular faces and also has a triangle for the base.
The faces of a cube are all the same shape - a square.
Only if it is a regular pentagon. The pentagon is in the shape of an equal legged pentagon, but, due to human error, the pentagon's interior angles may not all be exactly equal.
i think its the triangle because the base is square and all the faces is triangular shaped so its the triangle
