How many triangles in the picture answer 

• So, there are 8 lines in the picture.
• A triangle has 3 lines, therefore the equation will be 8 choose 3. That is also written as 8C3 in the format of nCr or nCk.
• Now the answer to 8C3 = 8*7*6/(3*2*1) = 56 but in the image, there are 6 lines where 3 lines coincide (6 ways of picking 3 lines removed) and a point where 4 lines coincide (4 ways of picking 3 lines removed, as there are 4 ways of choosing 3 lines among those 4 lines). You need to keep in mind that a triangle cannot be made when 3 lines coincide.
• Next, there are two sets of pairs of lines which do not meet. For each pair, choosing two lines of the pair and picking any other line will not make a triangle. So 6 ways of choosing 3 lines removed for each pair.
• So if we subtract 6, 4, and 2 from the equation then the equation will be 8C3 - 6 - 4 - 2*6  that is equal to 56 - 6 - 4 - 12 = 34. 
• Hence there are 34 triangles in the picture.
