How many different triangles are there in the figure shown above?
There are 3 rectangles with two diaganols each. Thus, each rectangle contains 8 small triangles. so total triangles are 24. Further looking at the first 2 rectangles as a single entity there are 2 triangle (1 at the bottom and 1 at the top) and similarly looking at the 2nd and 3rd rectangle there are another 2 triangles (1 at the bottom and 1 at the top) so total triangles are 24 + 2 + 2 = 28
