Off to the muppets with you young man.

 

odd

 

This requires someone with enough time to print and cut out shapes...

 

Yeah I do!

Sussed it!! answer in a bit!

The top one hasnt a straight edge along the slopeing side.......
Now got finger prints all over me monitor!![img]images/smilies/mad.gif[/img]
Looked a bit stupid too

 

Thanks Pavlo,none have got straight slopeing sides,feel a bit daft now
Ill get me coat.........

 

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

 

Yoza, you were half right man....

 

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
