I. LEARNING OBJECTIVES
During and at the end of the lesson, students are expected to:
1. illustrate the unit circle and relationship between linear and angular
measures of a central angle in a unit circle using Angle Meter and Infinite
Unit Circle mobile applications;
2. convert degree measure to radian measure and vice versa using
Trigonometry 3 app; and
3. Relate how angles are form to focus.

side in counterclockwise rotation?
Very good!
Notice as well that the angle is drawn in
the xy-plane with its vertex at the origin
and its initial side on the positive x-axis,
thus the angle formed is said to be in
standard position.
Are there angle measures given when you Yes, there are. Angles are expressed in

Trigonometry 3 Navigation:
1. Open the Trigonometry 3 app.
2. Go to the “Degrees to Radians”
tab to start learning how to convert
angles in degree measure to radian
measure. Once finished, go to the
next tab “Radians to Degree” to
start learning how to convert angle
in radian measure to degree
measure.
3. To answer question, simply tap on
a box (green box) to change the
number or symbol inside the box.
4. Then check your answer by
tapping on the tick.

F. VALUING
A while ago, I ask you to form an angle
using Angle Meter. Some of you failed,
while others have successfully formed an
angle. You notice that a minute movement
causes the angle measure to change. In
that particular scenario, what you really
need is FOCUS. Once you are focus on
your goals, you will definitely get what
you are aiming. For example, when you
are studying, make sure you are out of
distractions in order for you to focus.
Can you give me some of your priorities, (Students will give insights)
aims in life, etc. that you need to focus
on?
