Want this question answered?
the angle of elevation would be the angle between the horizon and the line of sight to whatever object you are measuring to. Lets say for instance that you see a plane, and you determine that it has an angle of elevation of 30 deg. This means that from the horizon, you would need to look up at an angle of 30 degrees to see that plane. below I linked to a diagram which illustrates it quite well. Hope this helped!
It means a corner, or a plane angle.
It depends on the angle of attack of the wing.
Any space can be divided into 4 quadrants basically using two mutually perpendicular planes - the horizontal plane(HP) and the vertical plane(VP). These planes are considered to be transparent and to be of infinite size. In first angle projections, the object is considered to be in front of VP and above HP. Hence the top view or plan of the object will be obtained below the reference line and the front view or elevation above the reference line. In third angle projections, the object is said to be behind VP and below HP. hence the top view or plan will be obtained above the reference line and the elevation below the reference line.
MMPA stands for maxillary mandibular plane angle.
An airplane over the Pacific sights an atoll at a 23 degree angle of depression. If the plane is 445m above water, how many kilometers is it from 445m above the atoll?
The angle of friction is defined as the angle of a plane where a body placed on the plane will start to slide.

"Perpendicular" means at an angle of 90° to a given line, plane, or surface.
normally above 10,000 feet and below 41,000 feet above sea level
All sections are obtained when a plane intersects the cones.If the plane is parallel to the plane of the circle which generates the cones the section will be a circle.If the plane is inclined to the above plane at an angle that is less than the angle of inclination of the cone, you will get an ellipse.When the inclination of the plane equals the inclination of the cone you will get a parabola.Finally, if the inclination of the plane is greater than the inclination of the cone, you will get a hyperbola.
incidence : it means the angle that goes in a objectrefracted : is where it changes inside an objectemergence : is the angle that come out the objectWhen the incoming light ray hits a plane, the angle of incidence is the angle between the incoming light ray and the normal of the plane at where the ray hits.
