12LEE Why did you deleate your answer?
so wot you were wrong no big deal,i was half wrong too....
Found it difficult with a CD case to see the slopes were not straight,the fact that the monitor screen is convex didnt fcukin help either

The left most angle of the three triangles should be exactly the same if the smaller triangles are part of a bigger one (theory of similar angles or whatever it's called - O-level maths). If we take the Tan of each angle, the ratio should be exactly the same. Tan of Angle = Length of Opposite
Side / Adjacent.
Angle of the larger one (A)
Tan (A) = 5/13 = 0.384615384615384615384615384615385
Angle of the smaller ones:
Tan (B) = 2/5 = 0.4
Tan (C) = 3/8 = 0.375
There you go
