II. LEARNING ACTIVITIES
Teacher’s Activities Pupils’ Activities
A. Preliminary Activities
Ok class let’s review our lesson yesterday
What is right triangle again, what is it class?
give one and draw it on the board
Acute triangle (the student draw an
example of an acute triangle.
What kind of triangle is this?
Now let us move on to the third types of a
The right triangle
Do you have an idea about a right triangle?
Have you heard it before?
( POWER POINT PRESENTATION &
Now, let’s have a game called “ARRANGE
I will divide the class into four groups. Each
group will have three representatives. You are
going to arrange yourself according to what I
am going to say.
Are you ready?
Arrange yourselves according to:
a. Your height
b. The length of your hair
c. Birth Month
d. Size of your foot
After each item, the teacher will emphasize the
difference of their sizes and length.
The group with the greatest earned points will
1. Find the length of one leg of the
Not yet Ma’am
That is a scalene triangle
No sides are equal
a = ? , b = 16 , c = 20
Since one leg is missing we have to ,
Manipulate/modify the formula in order
to find the missing part.
So we have that formula
Solve for the unknown parts of the Triangle.
Enclose your final answer.
b = 3
c = 15
2.) a = 6
b = 8
