1. REVIEW
Class, do you remember our past lesson Yes, Sir!
last week?
And what was that lesson? Our previous lesson was all about
trigonometric ratios sir.
Now, who can explain further about The trigonometric ratios are special
trigonometric ratios? measurements of a right triangle. The
two sides of a right triangle which
form the right angle are called the
legs, and the third side, opposite the
right angle is called the hypotenuse.
2. MOTIVATION
This morning, we will have a new lesson, Yes, Sir!
but before that we will have an activity called
“Look up! Look down!”. Are you ready class?
a. Tall objects/structures
b. Short objects/structures
3. LESSON PROPER
Our lesson for today is all about Angle of
Elevation and Angle of Depression.
But first, we must know what is a line of sight The line of sight is a straight line
is.? Who has an idea based on our activity and along which an observer observes an
from the world itself? object. It is an imaginary line that
stretches between observer's eye and
Very well said! the object that he is looking at.
What about the Angle of Depression? If the object is below the level of the
observer, then the angle between the
horizontal and the observer's line of
sight is called the angle of depression.
who can tell to the class what is an angle of The angle of elevation is an angle
elevation? between the horizontal and the line
from the object to the line of sight..
Then, what about the angle of depression? If the object is below the level of the
observer, then the angle between the
horizontal and the observer's line of
sight is called the angle of depression.
