Angle of elevation is looking upwards to an object and angle of depression is looking downwards to an object
angle of elevation is looking at an object above you while angle of depression is looking at an object below you
An angle is formed when two lines meet at a point.
measure
the circle has equidistance and it has no angle and sides while the polygon has sides and angle
A solid angle is 3-dimensional, a planar angle is 2-d.
explement of the angle or conjugate of an angle
It is the alternate angle to the angle of elevation
A sextant.
The difference of these two is that pullback is how far and launch angle is the elevation. I'm not sure but you can check on Science Buddies or just google it .
you could do a model showing the angle of elevation and angle of depression of a building

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.
It can be any object that is above or below the horizontal from the perspective of a viewer.
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)
Your missing the angle of elevation or depression.
distance and angle of elevation are closely related as the more closer you move, the half is the angle of elevation. for e.g. if you travel 30m and cover 15m then, the angle of elevation will be half of what you started with. this can be also proved by a live example as when you have the angle of elevation as 90 degree, then the distance can be zero....
This angle is termed as Altitude.
The angle of depression of a point is the angle between the line joining that point and the point of observation and the horizontal from the point of observation.
