Let us discuss each of them in detail in the following sections.Ī straight line on the flat surface where all points lie on a line and those points will have the same y-coordinate value. The three most important terms used in this concept are angle, horizontal line, and line of sight. This elevation angle is helpful to find the distance, height of the building with the trigonometric function like sine, cosine, and tangent. Thus we can use the trigonometry concept to find the distance from the observer to the object.Ī student named Rakesh is looking at a bird sitting at the building, then there is an angle formed, which is inclined towards the bird from the Rakesh eye. By joining the imaginary line between the object and the end of the horizontal line, it forms a right-angle triangle. The line in which the observer’s eye is there is known as the line of sight.įrom the above image, you can see that the observer is looking at the object from the ground making an angle θ with the line of sight and horizontal line. The angle of elevation of an object seen by the observer is the angle formed between the horizontal and the line from the object to the observer’s eye. The different terms used in the angle of elevation concept, trigonometric formulas, and solved examples are mentioned below for the sake of students. It is a widely used concept and it is related to height and distance. Finally, the angle formed above the surface. The angle of elevation is defined as the angle between the horizontal plane and oblique line from the observer’s eye to an object which is located above his eye. If two straight lines coincide at a point, then it is called the angle.
