1. Polygons and Solids

6. Helix - Volume or solid of spiral shape that turns at a constant angle. cylinder -Volume or solid generated by the rotation of a straight line) moving along a curved line. regular octahedron -Volume or solid with eight triangular sides of equal area; it has six vertices and 12 edges. parallelepiped -Volume or solid with six sides (parallelograms) that are parallel in pairs. cube -Volume or solid with six square sides of equal area and six equal edges; it has eight vertices. pyramid -Volume or solid generated by straight lines (edges) connecting the angles of a polygon (base) to the vertex and whose sides form triangles. cone -Volume or solid generated by the rotation of a straight line along a circular line from a fixed point (vertex). torus -Volume or solid generated by the rotation of a circle at an equal distance from its center of rotation. Sphere -Volume with all the points on its surface the same distance from its center; the solid thus delimited is a round ball. hemisphere -Half sphere cut along its diameter.

13. Diagonal-A segment connecting any two non consecutive vertices. So, if you join two vertices of a polygon which are not already joined by an edge, you get a diagonal.
