First angle projection places the object between the observer and the plane of projection, meaning the top view is below the front view, and the right side view is on the left side of the front view. In contrast, third angle projection positions the object behind the projection plane, resulting in the top view being above the front view and the right side view appearing on the right side of the front view. To interpret these drawings, one should remember the placement of views relative to each other based on the projection method used. Familiarity with these conventions helps in accurately visualizing the three-dimensional object from its two-dimensional representations.

What is the difference between first and third angle drawings?
It is just where the elevation is positioned, first angle, the drawings is positioned to the right of the section and third, the elevation is positioned to the left of the section, obviously rotated the correct way too.
What is the difference between first and third angle protection?
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.
How do you interpret first and third angle projection?
The front elevation is in the centre in both projections. In 1st angle projection the end elevation is on the opposite side of the front elevation and the plan view is below the front elevation. In 3rd angle projection the plan view is above the front elevation and the end elevations are on the same side as viewed
Why you not using 2nd and 4th angle projection?
Second and fourth angle projections are rarely used in technical drawing because they can lead to confusion and misinterpretation. These methods do not align with standard practices, which favor first and third angle projections for clarity and consistency across industries. By adhering to the more commonly accepted projections, engineers and designers ensure that their drawings are easily understood by others. Thus, using first and third angle projection simplifies communication and reduces the risk of errors in manufacturing or assembly.
How do you Explain two procedures that you can use to draw adjacent angles with given measurements?
To draw adjacent angles with given measurements, you can use a protractor and a compass. First, use the protractor to measure and draw the first angle by placing the protractor's center point at a vertex and marking the desired angle. Next, place the compass point at the vertex of the first angle, draw an arc that intersects the angle's rays, and then use the protractor again to measure and draw the second angle adjacent to the first, ensuring the two angles share a common vertex and side. Alternatively, you can use a straightedge to construct one angle, then rotate the straightedge to the desired measurement for the adjacent angle, ensuring they are connected at the vertex.
How do you interpret first and third angle drawings?
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.

How long people have been drawing?
Early man would draw on cave walls using charcoal (burnt sticks) and other materials. These drawings would record and explain events like a hunt or a battle. These are the first known drawings.
Where were the first drawings found?
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!
What was the first drawing?
Cave drawings.
To trisect a right angle you first construct an triangle?
equilateral * * * * * * * No its right. Apex is stupid in ways no one can explain so yeah...

What is the disadvantage of using isometric drawings?
One disadvantage of using isometric drawings is that they can sometimes distort the true dimensions of an object, making it challenging to accurately represent the size and proportions of the object. Additionally, isometric drawings can be more complex to create compared to other types of technical drawings, such as orthographic projections. Lastly, isometric drawings may not always provide all the necessary information needed for precise engineering or design purposes, as they do not show all sides and angles of an object simultaneously.
Is there a picture of the first car ever made?
there are drawings
How do you interpret first and third angle projection?

How did drawings began?
For one thing, drawing began way long time ago. The caveman was the first historic human drawings
