One type of illusion that really demonstrates how you view lines would be broken line illusions. This category of illusions tests your vision and analyzing skills. These illusions also skew your spatial recognition by interrupting lines. To understand what I mean look at the illusion below.
Do the back arches meet up perfectly?
Although it may not seem like it, the arches do meet up! The arches in the front break up the arches in the back which caused your brain to believe that they didn’t meet up.
Another illusion like this is shown below:
Which line connects to the line of the left?
The answer is line b!
