What is the Fold Test?

Symmetry & 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 the shape and fold it along an imaginary straight line so one half matches the other.
.
If the shape matches itself exactly it has bilateral symmetry.
.
If the shape does not match itself then it 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 tend to get very upset if you tried to fold them in half ­čÖé

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.
