In a first angle projection, the object stands in between the observer and the plane of projection. In a third angle project, the object and the plane of projection is interchanged.
In first angle drawings, the front view is on the lower left, with the side view to its right and plan view above it. On a third angle drawing, the front view is to the lower right, with the side view to the left and plan view above it. The metric system of measurement is based on a base 10 plan, with each unit having specific multiples that are powers of ten, e.g., kilo, meaning 10^3 units or milli- meaning 10^-3 units. In contrast, the imperial system uses varying lengths, such as 16 ounces in a pound or 12 inches in a foot.
Complementary angles are angles whose sum is 90° . Consequently, the value of any one angle can be any number less than 90°. The value of the second angle is the difference between 90 and the value of the first angle.
The first is two angles and the included side whereas the second is two sides and the included angle!
Difference between first shifting and second shifting theorem
Both third angle and first angle projection display the standard three orthographic views of a part or assembly on a drawing.. The key difference between third angle and first angle is the layout of the part on the sheet.
In a first angle projection, the object stands in between the observer and the plane of projection. In a third angle project, the object and the plane of projection is interchanged.
First angle is interpretted by the drawing being positioned to the right of the section and third angle is interpretted by the elevation being positioned to the left of the section.
A supplement to an angle in Geometry is a second angle with a size equal to the difference between 180 degrees and the size of the first angle. If the size of two angles is 180 degrees, then the angles are 'supplementary".

relation between critical angle and polarising angle?
Difference between first shifting and second shifting theorem
It depends... the first drawings were said to be found in the caves of the Aboriginal tribes in Australia, but there are also early drawings in Egypt that were called heiroglyphics. Thankyou!
There is lot of difference between test flight/air test/first flight.
