Measurements of regular hexagon

The regular hexagon has both reflection symmetry and rotation symmetry.

Reflection symmetry is present when a figure has one or more lines of symmetry. A regular hexagon has 6 lines of symmetry. It has a 6-fold rotation axis.

Rotation symmetry is present when a figure can be rotated (less than 360°) and still look the same as before it was rotated. The center of rotation is a point a figure is rotated around such that the rotation symmetry holds. A regular hexagon can be rotated 6 times at an angle of 60°

Hal, Zelda, Maya, and Jason each recorded the height and age of five classmates. They used the data to create the tables below.

A table (relation) may or may not represent a function

The table that represents a function is Hal's table

<h3><u>Tables and relations</u></h3>

For a table to represent a function, then the input values must point to exactly one output value.

This means that:

Each height entry must correspond to exactly one age entry

From the given tables (see attachment), we can conclude that

Hal's table represents a function
