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.


What is difference between 1st angle and 3rd angle projection?

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.


What is the measure of the third angle of a triangle if one angle measures 52 degrees?

The third angle is (128 degrees) minus (the second angle).

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.


The measure of the second angle of a triangle is 21 degrees more then the measure of the first angle the measure of the third angle is 15 degrees less than the measure of the first angle. each is?

Let the measure of the first angle be x⁰. So that the second angle would be (x + 21)⁰, and the third one would be (x - 15)⁰.Since the sum of angle measures in a triangle is 180⁰ we have:x + x + 21 + x - 15 = 1803x = 174x = 58Thus, the first angle is 58⁰, the second angle is 79⁰, and the third angle is 43⁰.

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.


The second angle of a triangular parking lot is four times as large as the first angle The third angle is 45 degrees less than the sum of the other two angles How large are the angles?

First angle=X Second angle=4x Third angle=5X-45 Since the angles of a triangle always = 180o x+(4X)+(5X-45)=180o 10X-45=180 10X=225 X=22.5 Therefore. . . First Angle=X=22.5o Second Angle=4X=90o Third Angle=5X-45=67.5o


The measure of the first angle of a triangle is 48 degree.the measure of the second angle is 32 degree .what is the measure in degrees of the third angle?

100.


What if The second angle of a triangle is 20 degrees greater than the first angle. The third is twice the second. Find the three angles.?
