What is the Fold Test?

The Fold Test is an easy way to see if something has reflectional symmetry. All you have to do is cut out a shape and fold it along an imaginary straight line so one half matches the other side.
Symmetry & the Fold Test
.
If the shape matches exactly it has bilateral symmetry.
.
If the shape does not match then the shape is not symmetrical.
.
Most of the time we do the fold test in our minds i.e. we imagine folding the object. Most real life animals would get very upset if you tried to fold them in half hehehe

What is a Reptile?Symmetry Example - Lizard

Reptiles are cold-blooded animals. This means their internal temperature depends on the temperature of their surroundings. Reptiles have backbones so are also classed as vertebrates. The skin of a reptile is covered in scales or hard protective plates. Lizards, snakes, turtles, crocodiles, alligators & iguanas are all reptiles and they all have bilateral symmetry.
