Week 10 lab:

1)  Use the Triangle Explorer activity at http://www.shodor.org/interactivate/activities/TriangleExplorer/ on level 2.  Determine the area of the triangle.
	Use the "Hint" button.
	Copy the triangle and the resulting rectangle from the "hint" onto the grid paper provided and label all side lengths of the rectangle.
	Use the Pythagorean theorem to find the missing sides of the triangles contained within the rectangle.
	Find the area of the two "blank" right triangles.
	Find the area of the rectangle.
	Using the areas from the two bullet points above, find the area of the red triangle and check your answer.
	Be sure to show your work so you can go back and review how you solved the problem.
	Complete 4 problems correctly.

2)  Use the Surface Area and Volume activity at
http://www.shodor.org/interactivate/activities/SurfaceAreaAndVolume/
a)  In words, describe what surface area measures and describe what volume measures.  
b)  In the “explore mode” move all the sliders to “1” with the rectangular prism.  
c)  What is the surface area?  
d)  What is the volume?  
e)  Change one dimension at a time by one unit and keep a table of the resulting values.  
f)  What is the formula for volume of a rectangular prism?  
g)  What is the formula for surface area of a rectangular prism?

3)  Download the Geogebra sketch from the week 10 page of the website and the Week10 extension.  Angle α (alpha) is 90 degrees.  Complete the chart. You will need a scientific calculator - you can use the calculator on the computer, start->accessories->calculator.  Be sure you are in the "scientific" view.  And make sure you the radio button deg (for degrees) rather than rad (for radian) is selected.
