## Problem 1: Use the applet below to answer the following questions.

Create line AB
1. Click on the third icon, click on line
2. Click on point A then point B
Create line BA
1. Click on the third icon, click on line
2. Click on point B then point A
What conclusion did you come up with?

## Making a line.

## Problem 2: Use the applet below to answer the following questions.

Create ray AB
1. Click on the third icon, click on ray
2. Click on point A then point B
Create line BA
1. Click on the third icon, click on ray
2. Click on point B then point A
What conclusion(s) did you come up with?

## Making a ray

## Problem 3: Use the applet below to answer the following questions.

Create ray AB
1. Click on the third icon, click on ray
2. Click on point A then point B
Create line BA
1. Click on the third icon, click on ray
2. Click on point B then point A
What conclusion did you come up with?

## Making a line segment.

## Problem 4: Use the applet to answer the following questions.

1. In order to create a plane, click on the fourth icon, then click on any three points. Your objective is to create the blue and the pink plane and give a generalization about what you observed.
(If your graph starts getting crowded, click the refresh button to start from scratch. To look at the graph from a different perspective click on the 5th icon, click on rotate 3D graphics view. Play around with the functions so that you get use to it.)
2. Create 2 lines using any two points on the diagram. What type of intersection was created. (i.e. point, line, line segment, ray, opposite rays or plane.)
3. Create line HA. What type of intersection does line HA and the pink plane create? (i.e. point, line, line segment, ray, opposite rays or plane.)
4. What type of intersection does the pink and blue plane create? (i.e. point, line, line segment, ray, opposite rays or plane.)
