1. ## It may take you a little bit of time...

Kinda trippy

2. Owe, you hurt my brain.

3. It's a triangle.

4. That is weird.

5. feung sheui.

6. LOL. Had this question in my GR12 class.. forgot the answer now but I remember it was damn easy.

;0)

_Haze.

7. if you take a close look, the slopes of the two triangles are different (one is convex slightly, the other concave slightly). The difference between the two equals the square. Just take a look at the slope on the first triangle where the green, red and orange meet.....it's exactly on the grid intersection....and on the second triangle, it's slightly above....

8. The two large assembled "triangles" are different. If you look closely, the slopes of the slanted side of the green and red triangles are different (one is 2/5 and the other 3/8). Therefore, the length along the two slanted sides of these two triangles is not straight and so the assembly large "triangles" are not triangles and are actually different in shapes (although very very subtly). Thus the formula used to calculate triangular area (1/2 x base x height) does not apply here.

9. >How can this be true?

solar wind =)

10. The tops of the assembled triangles aren't a straight line. The top one bends in and the bottom one bends out.

11. i printed it out and cut the two triangles out...they overlap...

no bendy bendy...try it

12. Nope. Read Marr's post and look at the pic carefully.

13. I'm still scraching my head on this one

14. Look harder to see that the slopes (RISE / RUN) are different. Since there are still a lot of confusion, do the area calculation by sum of parts to see that they are the same.

The shapes in UPPER and LOWER pictures are identical.

RED TRIANGLE: Area = 1/2(8 x 3)=12 sq. units
DARK GREEN TRIANGLE: Area = 1/2(5 x 2)=5 sq. units
LIGHT GREEN SHAPE: Area = 8 sq. units
MUSTARD YELLOW SHAPE: Area = 7 sq. units

TOTAL AREA = 12 + 5 + 8 + 7 = 32 sq. units for either

picture.

15. We need some engineering students in here. After that, go redesign the Lions Gate Bridge

edit- Yea, I finally see the diff. the slope of the bottom triangle is definately higher than the top one. But now I'm all cross-eyed
