An inverted "T"
┴ that one. Sometimes it'll have a small square to indicate a right angle.
Well the kites of our countries are simple that have no perpendicular lines,but the kite that are used in USA have perpendicular lines!!! Thank you!
The symbol of a cross with lines through it represents the concept of negation or rejection. It is commonly used to indicate that something is not allowed or prohibited.
The symbol used to indicate the end of a piece of music in sheet music is called a double bar line, represented by two vertical lines.

The symbol for parallel lines is two vertical lines (‖). It is commonly used in mathematics and geometry to indicate that two lines are parallel to each other, meaning they will never intersect, no matter how far they are extended. This symbol helps convey relationships between lines in diagrams and equations.
Line segments, perpendicular lines, and intersecting lines.

Thin unbroken lines used to indicate dimensions are?
Well, they are used for graphing information on graphs and are used on maps.
Set squares are useful for drawing parallel lines and perpendicular lines.
Hachured lines are used in cartography to indicate the slope or steepness of terrain on topographic maps. The direction of the hatching shows the steepness of the slope; lines that are closer together indicate a steeper slope, while lines that are farther apart indicate a gentler slope. Additionally, hachured lines are often oriented perpendicular to the contour lines to represent the direction of the slope downwards. Proper use of hachured lines helps convey the three-dimensional nature of landforms on a two-dimensional map.
