Geogebra and Chapter 1/2 Exploration
Exploration 1
1. Create 2 Points (A and B) Note: Geogebra should label the points automatically. You can also rename the points by double clicking on the point.
2. Create a line through points A and B
How many lines can you create that go through both points A and B?
How many points are needed to create a line?
Exploration 1 ctd.
3. Using a Line Tool, create Line CD with Point D lying on Line AB
What is the intersection of these two lines?
Exploration 1 ctd.
4. Create a line parallel to Line AB
What does parallel mean?
Exploration 1 ctd.
5. Create a line perpendicular to Line CD at Point C
6. Measure an angle at Point C
What does perpendicular mean?
Exploration 1
Exploration 2
1. Create Segment AB
2. Create a Midpoint of Segment AB
3. Find the Length of Segment AC and Segment BC
What is a midpoint?
Exploration 2 ctd.
4. Create the Perpendicular Bisector of Segment BC
What is a segment bisector?
Exploration 2
Exploration 3
1. Create three points (A, B, and C)
2. Create a Plane through Points A, B, and C
How many points are needed to create a plane?
How many planes can be created through three (non-collinear) points?
Exploration 3 ctd.
3. Create Point D on the Plane
4. Use the Detach Point Tool to move Point D above or below the plane
5. Create a Plane through Points A, B, and D
6. Intersect the two planes
What is the intersection of the two planes?
