A polyhedron is a solid object bounded by polygons. Polygons are plane shapes [bounded by straight lines]. The curved surface of a cone is not a polygon and so the cone is not bounded by polygons and therefore, a cone is not a polyhedron.
A triangular pyramid has 6 edges.
Slate splits into sheets and is used on roofs.
One whose boundaries are straight lines.
They are an interesting nice solid geometric shape with straight lines and pointy corners.
The solid breaks at random places. Apex. thanks guy below for leading me to this answer
No. A polygon is a plane area bounded by straight lines. The key term in this context is "plane". It is, therefore, 2 -dimensional shape. A solid, which is bounded by faces that are polygons, is called a polyhedron (plural = polyhedra).
Without the Sun's gravity and heat they would all go off in straight lines and freeze up solid.
In the US, both solid white lines and double white lines are used to mark areas of prohibited lane changes in multi-lane traffic. Broken (dashed) yellow lines, solid yellow lines, and double yellow lines are used to separate traffic moving in opposite directions.
an amorphous solid
Put the patterns in each of the blank spots that is the complete opposite of the pattern across from each spot. For instance, if there is a line with a break, put in a solid line instead. So, the top one (opposite bottom) should be three solid lines. The left one should be a broken line on top, and then two solid lines, and the right one should be two solid lines on top and then a broken line on the bottom. See related link for screenshots.

You have to count the lines on a solid figure
