What is the ratio of squares to triangles?
1:2
How many triangles are in a 14 gon?
There are 2160 degrees 1n a 14-gon and 180 degrees in a triangle and 2160/180 = 12. Answer: 12 triangles

How many angles does the icosahedron have?
A regular icosahedron has 20 faces (equilateral triangles), 30 edges and 12 vertices.
What is the hypotenuse of an equalateral triangle with 12 foot sides?
If you divide the equilateral triangle into two right angle triangles then the hypotenuse will be 12 feet.
What has 8 congruent equilateral triangles as faces and 6 vertices?
A solid with 8 faces is an octahedron.As all faces are the same it is a regular octahedron.As such it is one of the five platonic solids - the only five 3D objects that can be regular: the tetrahedron (4 equilateral triangles for the faces), the hexahedron (usually called a cube with 6 square faces), the octahedron (as asked, 8 equilateral triangles for the faces), dodecahedron (12 regular pentagons as faces), icosahedron (20 equilateral triangles as faces).
How can you remove 4 toothpicks from 16 toothpicks to get 4 congruent triangles?
Fuor toothpicks from 16 leave 12 which, by coincidence (?) is exactly enough for four equilateral triangles!
What are the regulars?
The plural of "polyhedron" is "polyhedra." There are only 5 regular polyhedra:Tetrahedron, 4 sides, all equilateral trianglesCube (or hexahedron), 6 sides, all squaresOctohedron, 8 sides, all equilateral trianglesDodecahedron, 12 sides, all equilateral pentagonsIcosahedron, 20 sides, all equilateral triangles

What are the three types of polygons that can be the faces of a Platonic solid?
The polygons are the equilateral triangle, the square, and the regular pentagon. The faces of these platonic solids are made from the following polygons: tetrahedron - 4 triangles cube - 6 squares octahedron - 8 triangles dodecahedron - 12 pentagons icosahedron - 20 triangles
What is the proper pin spacing for ten pin bowling?
Pins are arranged in a series of equilateral triangles with the distance centre to centre between each pin being 12 inches.
Is it possible to make1 cube with 9 matchsticks and how?
Not possible. A cube has 12 edges.
