Missing Hole Triangle Answer

This answer borrowed from The Scientific Psychic.
The area of a right triangle is computed by multiplying the base times the height and dividing by two. The pieces of the puzzle have an area of 32 square units. Although they can be assembled to form what appears to be a 13×5 right triangle, they actually form quadrilaterals that are slightly smaller or slightly bigger than a 13×5 right triangle.

The top figure has an area of 32 square units. The bottom figure, including the empty square, has an area of 33 square units. A real 13×5 right triangle would have an area of 32.5 square units. The distortion is difficult to see because one square of the picture is approximately 3% of the area.

The distortion can be seen more clearly when the empty square constitutes a larger percentage of the area, as in the figure below where 1 square represents 13% of the area.

Pass the Ball

This is a two post illusion if you didn't read the first post go there now.

How many times was the ball passed? The answer to that can wait. Without looking again, what else did you see in the movie?

How many elevators were there?

What was the graffiti on the wall.?

Did you see any animal or animals pass through the scene? Maybe a kangaroo, a horse or a gorilla?

If you can't remember what animal passed through the set go back and watch it again, this time don't worry about the basketball. Once you figure it out don't tell your friends and spoil it.

Still wondering how many times the ball was passed or what animal did an Alfred Hitchcock cameo through the movie? Check out the comment section below.

Other stimuli from their studies of change blindness and inattentional blindness can be viewed at Visual Cognition Lab at the University of Illinois.
