### Mathematical Optical Illusions

Don't let your brain be fooled by these geometric optical illusions in this online quiz. 8 mind-bending optical illusions and a brief explanation of how they work as well organizes its elements, such as shapes, sizes, colors, spatial relationships. Optical Illusions can use color, light and patterns to create images that can be deceptive or misleading to our brains. The information gathered by the eye is.

Would you believe that the two tabletops are exactly the same? If not, check out this animated illustration to see for yourself. First presented by American psychologist Roger Shepard in his book Mind Sightsthis simple yet astonishing visual illusion is further proof that our vision system is largely influenced by our experiences with the outside world and therefore interferes with reality sometimes.

The closer the object is in distance, the larger it is on our retina. The nonexistent triangle also appears to be brighter than the background, although they are of the same luminance. This illusionpopularized by Italian psychologist Gaetano Kanizsa, reveals how we tend to seek closure in our visual perception. Some of the best optical illusions are based on the principle that our brains are trained to fill in the gaps between shapes and lines and perceive blank space as objects even when there aren't any.

How does this happen? The lines are joined at the end to create the illusion of a prong.

And because our minds tend to reconstruct 3D imagery out of the flat 2D image, it creates the illusion of depth. Read more about how to become a better visual thinker here or effectively tell a visual story here. What are the best optical illusions you've found on the web?

Here's hoping that you'll be able to see through the lies and the fakery to find out exactly what it is that is happening on your screen. Sure, some of them will be easier than others, but we can guarantee that you won't get all of these without at least some knowledge of how the human mind can be fooled.

So, are you ready to take the optical illusions test?

## Mathematical Optical Illusions

Are you here to prove your ability or just have someone mess with your head? Whatever your reasoning, it's time to get started! Originally put to paper by an astrophysicist, this image highlights yet again how perspective changes or enhances the way that our brain sees images.

While the lines are parallel, the diagonal lines across them make us think that they bend away from each other. This is once again, quite worrying, as there is no way of knowing if a similar image made up of real life objects won't present itself when you really need to understand where things are in relation to each other.

True False 2These two objects are actually the same size. If the course of human history has taught us anything, it's that we are not able to comprehend everything perfectly with the limited set of circumstances we're given at birth. Seriously, the human brain is deeply flawed and the eye is not exactly perfect either, which is exactly why images like this confuse us.

So, are they the same size as we claim, or is your eye telling you they're different sizes for some reason? What do you think about it? True False 3None of the thin lines in this image are actually parallel.

Yes, this is an optical illusion that was created to teach you how the simplest answer can often be the correct one. While the adult part of your brain that wants to second guess what you're seeing is likely telling you that this is a trick, that the lines are actually parallel and straight but the white and black blocks change this, you'd be wrong!

This is actually a double bluff, and the thin lines were always diagonal, to begin with.

True False 4The orange circles are actually the same size. A lot of how we as human beings perceive things is down to perspective and how the objects and images around us interact with each other, which is why we end up with optical illusions such as this one. Due to the size difference between the blue dots, it appears as if the orange circles are different sizes, but this is our brain being fooled. True False 5The red lines are all exactly the same color. Now onto something that is working less with perspective and more with the brain's inability to see what a color truly is when placed next to a different one.

While it may be hard to believe, all of the red lines are exactly the same color and brightness, but their proximity to different colors highlights how our eyes don't always see color perfectly. Just the addition of a white or black line can completely change how our brain sees the image.
