All over the
country, mid term exams are looming over 28 crore school children like a Monster
They are burning
mid night oil , pouring over their text books and trying to figure out :
“ From this Chapter
, what questions are most likely to appear in the forthcoming exam ? “
That is tough
Even tougher is to
figure out :
“ If this question was to appear in exam paper
, what should be the RIGHT / CORRECT answer ? “
Hey, Parents :
I know , even some
of you are holding in your hands , exam papers of previous years , throwing a
question at your ( trembling ? ) child and expecting her to come up with that
RIGHT / CORRECT answer
And if she cannot,
woe befall her !
That need not be
Just ask her to :

How does a kaleidoscope work? |
A kaleidoscope works by using mirrors placed at an angle to create
multiple reflections of colored objects inside the tube. When you look
through the hole, these reflections form beautiful and ever-changing patterns
due to the reflection and symmetry principles involved. It's a fascinating
optical device that designers and artists often use for inspiration in
creating new patterns. |

Explain the correspondence of vertices
in congruent triangles |
In congruent triangles, the correspondence of vertices is crucial for
correctly representing their similarity. For example, if triangle ABC is
congruent to triangle DEF, we must ensure that each vertex corresponds
accurately. This means that point A corresponds to point D, B corresponds to
E, and C corresponds to F. By establishing this one-to-one correspondence between the vertices of
congruent triangles, we can symbolically represent their similarity as ∆ ABC ≅ ∆ DEF. It's important to note that under this correspondence, not all
permutations are valid. For instance, writing ∆ QRP ≅ ∆ ABC would be incorrect because it doesn't follow the correct vertex
correspondence. Therefore, when expressing the similarity of two triangles in symbolic
form or discussing their congruence criteria like CPCT (corresponding parts
of congruent triangles), ensuring the accurate correspondence of vertices is
essential for clarity and correctness in geometry studies. |
