write a conversation in between a teacher and a student on how we can make this world a more better place
Answers
Answer:
DEF are respectively the midpoints of sides AB, BC and CA of triangle ABC, then: Ratio of area of triangle DEF : area of triangle ABC = 1 : 4
Solution:
In the given question, we know Triangle DEF formed with midpoints is similar to the Outer Triangle ABC
On the basis of the similarity, we can say,
If two triangles are similar then the ratio of their area is equal to the square of the ratio of their corresponding sides
Mathematically can be written as :-
\frac{\text {area of triangle } D E F}{\text {area of triangle ABC}}=\left(\frac{D E}{A C}\right)^{2}
area of triangle ABC
area of triangle DEF
=(
AC
DE
)
2
Since, DECF is a parallelogram. So DE = FC
On substituting:
\frac{\text {area of triangle } D E F}{\text {area of triangle ABC}}=\left(\frac{F C}{A C}\right)^{2}
area of triangle ABC
area of triangle DEF
=(
AC
FC
)
2
Also, F is the midpoint of AC
\text { So } \mathrm{AC}=2 \times \mathrm{FC} So AC=2×FC
\begin{gathered}\begin{array}{l}{\frac{\text {area of triangle } D E F}{\text {area of triangle } A B C}=\left(\frac{F C}{2 F C}\right)^{2}} \\\\ {\frac{\text {area of triangle } D E F}{\text {area of triangle } A B C}=\frac{1}{4}}\end{array}\end{gathered}
area of triangle ABC
area of triangle DEF
=(
2FC
FC
)

area of triangle ABC
area of triangle DEF
=

Hence ratio of area of triangle DEF and triangle ABC is given as:
Ratio of area of triangle DEF : area of triangle ABC = 1 : 4

Conversation Between Student and Teacher About Future
Teacher: What are you planning to do after passing your matric?
Student: Sir, it would depend on what marks I get.
Teacher: Ok, so what have you planned if you secured good marks in matric?
Student: I will haunt pre-medical groups in F.S.C. Otherwise, I shall join I.C.S.
Teacher: Why did you deem medical groups?
Student: I think that several people die due to inadequate medical aid. They cannot afford substantial medical costs. I shall help them without exerting any charges.
Teacher: Your statements are false because each student shows pity first, but does not work upon his promise and grows materialistic.
Student: I would not be in that evil group. My grandmother was very ill, and we could not get here appropriately treated because we were destitute. My purpose in life is to be a doctor, and I shall serve the people as a good citizen and help the needy free of cost.
Teacher: Ok, then. Hope You will get succeeded in your life.

Student: I nearly finished it; however, I am facing a problem in understanding a few concepts.
Teacher: Let me know which area needs more explanation?
Student: In the last session, you taught me Adjectives. I have found that few adjectives are ending with ‘ed’ and few of them finishing with ‘ing’, but I am incapable know which Adjective is used at what place?
Teacher: The ‘ed’ adjectives are used to define our feelings and ‘ing’ adjectives represent the property of a person or a thing.
Student: So, when I say, I am confused, is it correct?
Teacher: No, Confused is the word because if it’s your feeling, then you need to add ‘ed’ to confuse and it becomes your feeling.
Student: Now I have learned, thank you so much, Madam.
Teacher: You are always welcome.
