Instructional Resource  Geometric Construction  Constructing an Egg Shape 
Instructional Resource  Geometric Construction  An Egg ShapeIn this instructional resource, we show the steps in constructing an egg shape. In the process, students learn about using common points of tangency to create smooth curves from two different shapes. This activity can be done with pencil, compass, ruler, and grid paper.

Closed Captioned Video: Geometry Applications: Circles, Segment 2: Circles and Arcs.The Roman Coliseum is a large elliptical structure. Yet, the Romans likely used circular arcs to build it. This segment explores the properties of circles and shows how arcs can be used to create elliptical shapes.
