In Geometer’s Sketchpad Tutorial 1, we have learned how to construct an equilateral triangle. In this tutorial, we will explore the relationship of a triangle with a moving vertex on a line parallel to its base. We will construct the drawing shown in Figure 1. In Figure 1, PQR is a triangle, QC is parallel […]

## Geometer’s Sketchpad Tutorial 1: Constructing an Equilateral Triangle

In this tutorial, we will use the Geometer’s Sketchpad to mimic the compass and straightedge construction tool we use in elementary geometry. Geometer’s Sketchpad is a proprietary interactive geometry software developed by Key Curriculum Press. The idea in constructing an equilateral triangle is to use the centers of two circles and one of their intersections […]
