The angle of elevation is defined as the angle formed between a horizontal line and the line of sight to an object that is above the horizontal line. It is measured from the observer's eye level up to the object. In mathematical terms, it can be expressed using trigonometric functions, where the tangent of the angle is the ratio of the opposite side (the height of the object) to the adjacent side (the distance from the observer to the base of the object).
The angle of elevation is looking at an object above your line of sight.
It is the alternate angle to the angle of elevation
If the base of the elevation is at a distance d from the observer, then the highest point is at a height = d*tan(angle of elevation)
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
i dont care about math even though i use it.
Angle of elevation is looking upwards to an object and angle of depression is looking downwards to an object
The angle of elevation is looking at an object above your line of sight.
It is the alternate angle to the angle of elevation
mathematical phrase
If the base of the elevation is at a distance d from the observer, then the highest point is at a height = d*tan(angle of elevation)
Corresponding Angle
Angle of elevation: tangent angle = opposite/adjacent and by rearranging the given formula will help to solve the problem
The angle of elevation is defined as the angle formed between a horizontal line and the line of sight to an object that is above the horizontal level. It is measured from the observer's eye level to the object. Essentially, it describes how steeply one must look up to see the object. This concept is commonly used in trigonometry and various fields such as architecture and navigation.
Angle of depression is defined as the angle between the horizontal line and the line joining the observer's line of sight to an object below the observer's eye sight. You can be on top of a building and an object is situated on the ground, and the angle between your horizontal line and the object is the angle of depression.
A sextant.
the change in elevation changes on record.
