Neglecting term "opposite".. In third angle projection, what we see are what are we going to draw
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.
The third angle of a triangle is equal to 180 degrees minus (the sum of the first two angles).
it depends on the first two: angle3 = 180 - angle1 - angle2
Let the first angle be x the second angle be 4x and the third angle be 80+4x+x: x+4x+80+4x+x = 180 Collect like terms: 10x = 180-80 10x = 100 x = 10 Therefore the measure of the second angle is 40 degrees.
In a triangle the measure of the first angle is four times the measure of the second angle. The measure of the third angle is 18 degrees more than the second angle. What is the measure of the first angle? 68 43 17 95
first angle projection and third angle projection.
any country using in second r fourth angle projection r else what r the advantages between first angle and third angle projetion
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.

right side view draw in left side and left side view draw in right side is called third angle projection
First angle and third angle projection are two methods of creating orthographic projections of 3D objects in technical drawing. In first angle projection, the object is positioned between the observer and the projection plane, resulting in the top view appearing below the front view and the right side view appearing to the left. Conversely, in third angle projection, the object is placed behind the projection plane, which positions the top view above the front view and the right side view to the right. These projection methods are standardized in different regions, with first angle commonly used in Europe and third angle prevalent in the United States.
First angle projection and third angle projection are two methods of orthographic projection used in technical drawings. In first angle projection, the object is placed in the first quadrant, meaning the view is projected onto the plane behind the object, resulting in the top view appearing below the front view. In contrast, third angle projection places the object in the third quadrant, with the views projected onto the planes in front of the object, making the top view appear above the front view. These conventions are used to standardize how drawings are interpreted, with first angle commonly used in Europe and third angle in the United States.

Third angle projection is in common use in the USA, Canada, and the UK. The rest of the world more commonly uses first angle. There is no inherent superiority of one projection over the other. When you are making drawings that may be used internationally, it's a very good idea to indicate by a small symbolic diagram which projection is in use. This diagram is usually a side and end view of a truncated cone.

thrid angle projection is officially used in Australia, for a fact, not lying!!
