Use for entity discovery:

Return a list of sample lamina entities:

Use to discover properties of a lamina:

Display a diagram of a lamina:

Find the properties of a lamina:

Return people associated with a lamina:

Create a table of variables determining the shape of a lamina, together with their descriptions:

Find classes of lamina:

Find lamina in a given class:

Diagrams and equations of area for a class of lamina:

Give a geometric region corresponding to an annulus:

Discretize and visualize the region:

Give an implicit geometric region corresponding to a square I-beam:

Discretize and visualize the implicit region:

Using LaminaData is equivalent to calling EntityValue on the corresponding entity and property:

Evaluate LaminaData with "Classes" argument:

The above is equivalent to evaluating EntityClassList of the entity type "Lamina":

Entity classes cannot be given as bare strings:

Specifying an explicit EntityClass works as intended:

This is equivalent to calling EntityList on the EntityClass:

Draw a lamina together with its incircle and circumcircle:
