**What is a rectilinear figure?**

In geometry, a rectilinear figure can be defined as a plane figure or shape all of whose sides meet at right angles.

The interior angle at each vertex of a rectilinear is 90 degrees (90°) or 270 degrees (270°).

Here, for instance, are a few irregular polygons that classify as rectilinear figures.

*Rectilinear figures are oh-so neat!*

*At right angles, all its sides meet!*

Instead of handing out colouring rectilinear figures worksheets, show your child pictures of different objects. Ask them to identify the objects in which they can see rectilinear figures and further justify their answers.
