Can you tell me in a simple way about the Poggendorf illusion?

We Answered:

Essentially, the lines at the sides lead the eye either inward or outward to create a false impression of length.

or:

The most common explanation is that we misjudge the angle at which the line intersects the rectangle. When we look at the figure, our brain increases the angle between the line and the rectangle, trying to make it closer to a right angle. By increasing the angle, the brain emphasizes the difference between the angle of the rectangle's side and the angle of the line. The brain often over-emphasizes differences.

How should I start my report?
