Activity 2 - K'NEX connectors
All KNEX connectors can be connected to at least one KNEX rod, and the largest can be connected to eight rods. To help gain familiarity with KNEX connectors, make the model shown below.
The angle between any two adjacent rods connected to a connector is 45 degrees. This makes KNEX very good for making shapes that have angles of 45 degrees, 90 degrees and 135 degrees, such as squares, rectangles, right-angled triangles and octagons, as you will see in the next few Activities.
