1. Introduction: The Composite Shape Design of the Petronas Towers

To start this lesson, watch this video about the Petronas Towers. Note the use of composite figures in the shape of the towers.

2. Creating a Composite Shape

Watch this video to learn how to construct the Islamic star shape found in the Petronas Towers using the TI-Nspire.

3. Analysis of the Composite Shape

Watch the video to learn how to calculate the area of the composite shape created in the previous section.

4. Analysis of the Enhanced Composite Shape

Watch this video to learn how to add the additional circular area to the design.
