Any sedimentary rock that forms, as sediments settle out of a solution, is called a chemical sedimentary rock. Sediments can settle out of a solution either by the liquid in the solution evaporating, or by too much of the sediment dissolving in the solution (called supersaturation).
A lozenge (â), often referred to as a diamond, is a form of rhombus. The definition of lozenge is not strictly fixed, and it is sometimes used simply as a synonym (from the French losange) for rhombus. Most often, though, lozenge refers to a thin rhombusâa rhombus with acute angles of less than 45Â°.
What Shape Is A Octagon. A trapezium Edit: Actually that's more like half a hexagon, not an octagon. I don't know if there's a name for half an octagon As it's a five sided shape it's a pentagon, those don't have to have matching angles and sides to be called that, any five sided shape is a pentagon.
