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