Choose the ‘Hyperbolic Perpendicular’ tool from the Custom Tools.

Exploring Geometry with the Geometer’s Sketchpad: Revised for Use with Version 4

Exploring Ratio, Proportion, and Probability in Grades with The Geometer’s Sketchpad This collection of Sketchpad activities allows students to explore concepts and develop skills related to: We do see that the segment does not leave the disk, which is accurate.

Construct a segment AB near the center of screen.

The custom tools are located under the Custom Tool button at the bottom of the Toolbar. Here we see the variety of special tools we will need. To measure angles, make sure to use the Hyperbolic Angle tool under the Custom Tools.

You also may like to try some of these bookshopswhich may or may not sell this item. This collection of Sketchpad activities is aligned to the High School Geometry Common Core State Standards, and covers virtually every concept studied in high school geometry. Each module is accompanied by an access code that allows you to download a collection of Sketchpad sketches.


If we move point A or B, we see that that the constructed line remains perpendicular. The software is very easy to use, the modern student with technological aptitude will have no difficulty in using Sketchpad.

Project 10 involves using geometry software to investigate Hyperbolic Geometry. We can use the Hyperbolic circle tool and the Hyperbolic distance to create circles with this property. Books by Dan Bennett. This collection of Sketchpad activities is aligned to the Common Core State Standards, and a full correlation of the activities to the High School Geometry Standards is available for download here. Like all mathematics, it requires significant logical reasoning skills, but those skills are helped when high quality diagrams are used.

None of your libraries hold this item. Key Curriculum Press, c Sketcbpad Number and Operations in Grades 3—5 with The Geometer’s Sketchpad This collection of Sketchpad activities is an excellent introduction to Sketchpad for both students and teachers, and gives students the opportunity to explore concepts in the Common Core State Standards grades from the domains of operations and algebraic thinking, number and operations in base ten, and number and operations—fractions.

This is the file PoincareDisk. Includes teacher notes and activity sketches for such topics as counting by grouping, measuring, balancing equations, similarity, adding integers, areas of triangles, and circle vocabulary.

As part of the project, we are to measure the summit angles. Found at these bookshops Searching – please wait Note that this segment does not look like a ‘normal’ Euclidean segment.

Mathematics grade 7, 8, 9.

Then, click skftchpad drag to create hyperbolic segment AB. Now, construct the hyperbolic perpendicular to AB at A. I am unable to find my version, version 5, on Goodreads. Hyperbolic Circles On page 46, we create circles in this geometry and notice that circles of different apparent sizes can have the same hyperbolic radii.

The remaining constructions and exercises in Project 2 should now be doable using the Hyperbolic Custom Tools.

Some of the activities are available in print, some are available sletchpad for download, and some are available through third-party links. I strongly recommend this book for either a traditional class, a directed study class or working independently.

The exercises are easy to understand and they are very directed in the sense that clear instructions are given.

Lines, segments, and circles have different definitions in this geometry, so we explornig have custom tools for constructing these objects. We can measure the length of the segment by selecting the ‘Hyperbolic Distance Measure’ item under the Custom Tool button.
