Video Tutorial

Here is a LINK to the applet I used to create the video for the Focus part of the lesson.

Investigate

Investigate an idea or problem, with a partner if possible.
The investigation provides the background for the ideas presented in the lesson.

TEXT Page 188

Read/Work through the  Investigate  section on Page 188 in your textbook.

You may not have a partner to work with.  
No worries!  
You can do this activity on your own.
Do your best to answer the questions, then watch the Video Tutorial for help or to check your answers.

Note!   It’s not likely you will actually get a triangular prism from your teacher.
In the video I will go through the activity using a computer model.

If possible share your thoughts/ideas/answers with another person.
If you can help them understand, then you likely have good understanding yourself.

Check questions require basic understanding of the ideas of the  lesson.

Apply questions will require you to dig deeper for a solution.

Take It Further questions offer enrichment and extension.
