Brace
A diamond is not a rigid shape unless it has a brace. A brace is a diagonal line you put inside shapes to make them rigid. Triangles are rigid so if you put a brace in a square to make two triangles the square is now rigid.
about an inch below the TOP of the filter...there should be a line on your filter...
No.
That means that the height should be measured perpendicular to some other line (or plane in some cases). For example, to calculate the area of a triangle, the formula is (1/2) x base x height, where the height must be measured perpendicular to the base.
A line !
It is the height of the perpendicular line from its vertex to its base
You can, but it depends on what you hope to show. A bar graph, showing the numbers or proportions of people within height bands may be a more effective visual display.
The height of collimation is the height of the line of sight. It is the vertical distance of the horizontal plane through a telescope.

A contour line indicates height.
a straight line...
