I been trying to make sence of this triangle thing for a few days now. I have calulated the area of the triangles and some how i keep getting 3 different answers for the total area, 31.5, 32, and 32.5. Can someone please help me crack this damn thing and help me with these odd total area answers. This is beginning to confuse me because it makes no sence visually or mathmatically. Or it could just be I'm dumb.

Glad I could be of service, that will be £10 please.
Please make checks payable to Mr. M. Thomas

Sure, just ignore the white powder in the envelop that the check comes in.:)

I've seen this before.....
The bottom left angle on the green triangle is about 1 degree bigger than the bottom left angle on the red one. So, when they put it together into a big triangle, its not really a triangle. There's a bend in the middle of the big side.

The Math:
The red triangle goes over 8 boxes and up 3 boxes.
The green one goes over 5 and up 2
so.....
8/3 does not equal 5/2. Therefore, the two trianges are not similar.

If you want to find the angles, use a little trig and use the inverse tangent on 3/8 and 2/5.

[edit]
Did I really just post that?
I'm such a dork.......:O
 
The first one has area 35u(nits)^2 The second one has 34u^2at first glance but its a trick. They are infact parralellograms. If you look closely the green triangle is 5/2 (opposite and adjacent sides)
and the red one is 8/3, these are not similar, (I think the previos guy explained. But since Im bored Ill tell you that the hypotenuse of the green one is the square root of 29.
 
Dont worry, knowledge of maths doesnt necessarily make you a dork, the fact I can work out the square of 3 digit numbers is a little scary though.
