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.
A line !
It is the height of the perpendicular line from its vertex to its base
The height of collimation is the height of the line of sight. It is the vertical distance of the horizontal plane through a telescope.
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.
Well, darling, perpendicular height is simply the vertical distance between a point and a line. It's like measuring how high you need to jump to clear a hurdle - no rocket science there. So, if someone asks for the perpendicular height, just give them the straight-up distance between the point and the line, and call it a day.
highest point-mount Everest height-8848m.
A contour line indicates height.
a straight line...
