Straight Line

Circle Ellipse Hyperbola Parabola
 
Analytic geometry of points and straight lines
Define, create and explore: points on a plane, midpoints of segments, distances between points, straight lines, parallel lines, perpendiculars, perpendicular to a line through a given point, distance from a point to a line, etc. The following screenshots were designed to meet the pedagogical approach needed for teaching and learning of these topics:

Topic 1 - The Slope

Topic 2 - Parallels

Topic 3 - Perpendiculars

Topic 4 - A length of a segment

Topic 5 - Mid point of a segment

Topic 6 - A distance from a point to a line

Dynamic movable tools, such as: Points, Segments, Straight Lines, Parallels, Perpendiculars, Chords, Perpendiculars from a point, Angles and Angle Bisectors.
Tracing while obtaining updated quantitative information for each location, and the dynamic tools, including the relevant equations.

Quantitative coordinate system (scales), fully user controlled by zooming in/out, dragging the axes and changing the scales.

Copy and Print: All the content can be easily transferred to a Word® document or to any presentation program such as Power Point® or to be printed directly.

A Help supplement to the software includes specified instructions for each of the software's components.

Performance and Features
The performance and features provided by the software for guided visual dynamic study the analytic geometry of points and straight lines, are illustrated by screenshots.
