CHAPTER 6: TRIANGLES SOLUTION AND EXPLANATION Introduction: The first thing is to know about the similarity. It is not like the congruency of triangles, which you have read in your 10th class. Here, things are a little different. Suppose that we want to draw a mountain in the notebook; can we draw it of a similar size as we see in reality? The answer is absolutely no! We draw it by taking some ratio on the notebook so it looks similar to the actual mountain. There are several examples like it. Another example is when we see a builder plans to make an apartment, and he starts with a raw model on the board, which is prepared with some ratio. Similarly, in triangles, we look for those figures that are in some proportion, not exactly of the same size.  Exercise 6.1 Questions Click here to access the special offer!  Answer 1: (i) All circles are similar.

  Simple explanation and solution to the arithmetic progression  Click here to access the special offer! What is an arithmetic progression?  Observe these series: Ex(1): 1, 2, 3, 4, 5, 6... Ex(2): 2, 4, 6, 8, 10 ... Ex(3): 1/2, 3/2, 5/2, 7/2... In example 1, you can see the difference between two consecutive terms: 2-1 = 1, 3-2 = 1, 4-3 = 1... and so on.  In example 2: 4-2 = 2                       6-4 = 2                       8-6 = 2 and so on. Similarly, the difference of the two terms in example 3 is 1/2. A series in which consecutive terms differ by a constant (fixed) value is called arithmetic series.  The first term is often represented by T1 or a, and the fixed difference is denoted by "d" If we observe this type of series, we can write it as: a, (a+d), (a+2d), (a+3d),... The first term contains no d, or it may be written as (1-1)d The second t...
