introduction to angles of elevation and depression every day we look at different things around us we look up to savings above us we look down to see things below us angles are formed when we look up or down and these angles are called angle of elevation and angle of depression first let's follow Dylan around the park to see the different angles of elevation and depression Dylan looks up and the bird on the tree when he looks up there is an angle formed let's find out where this angle is remember Dylan was looking straight like this just now then he looked up at the bird there is an angle here we say this is the angle of elevation elevate means to lift up with this angle of elevation of the bird from Dylan he takes a close shot of the bird next Dylan now needs to locate the crocodile farm he sees a signboard and he tilts his head again there is an angle of elevation of the signboard from Dylan's eyes remember Dylan was looking straight like this just now then he looked up at the signboard there is an angle here this is the angle of elevation Dylan cannot see the words clearly he walks nearer to the signboard the angle of elevation of the signboard from Dylan increases as he walks nearer to the signboard emeritus the crocodile farm is over there he walks to the coconut farm and the farm he sees the crocodile and he looks down at it when he looks down there is an angle formed let's find out where this angle is remember Dylan was looking straight like this just now then he looked down at the crocodile there is an angle here this is the angle of depression depressed means downwards with this angle of depression of the crocodile from Dylan he takes a picture of it he walks a few steps on the platform and sees a mudskipper opening its mouth Vette is a rare sight he tilts his head down to capture the picture again there is an angle of depression of the mudskipper from him this angle is larger than the angle of depression of the cocoon or from Devon because the mudskipper is nearer to dillon he took a picture of it now that we have seen angles of elevation and depression like this do you notice any similarities in them notice they're both angles of elevation and depression have a horizontal line notice there is also a line touching the horizontal it is this line that connects the object from the observers eye it's called the line of sight thus an angle of elevation or an anchor of depression is between a horizontal and the line of sight the angles are also at the reference point and the word from is important to determine the reference point heading on is there any relationship between these two angles let's continue following Dylan to find out Dylan sees a scribble on the tree there is an angle of elevation of the scribble from him here let's draw the horizontal end line of sight can you identify it hits is here interestingly the scribble looks back at Dylan there is an angle of depression of Dylan from the squirrel let's draw the horizontal end line of sight can you see it it is here since both horizontals are parallel and are cut by the same line these two angles are equal Dylan takes a picture of the scribble and walks on all in all when we look up an angle of elevation of the object from us is formed specifically angle of elevation is the angle between the horizontal and line of sight when we look down an angle of depression of the object from us is formed and an angle of depression is the angle between the horizontal and the line of sight to
