1. Play around with the three sliders labeled Base of Triangle, Height of Triangle, & Height of Prism. [br][br]2. Then click the box to the left of the word Start. Watch as the Triangular Prism Opens + Closes. [br][br]3. Stop the slider at the far left position. Then click on the triangular prism to rotate. Examine the net of the Triangular Prism.
Now your job is to derive a formula we would use to find the Surface Area of any Triangular Prism. [br][br]1. Close the Triangular Prism[br]2. Click the box saying Show Perimeter of Base[br]3. Open the Triangular Prism using the slider. [br]4. The Lateral Area forms a rectangle. The length of this rectangle is equal to the perimeter of the ________[br]5. The height of this rectangle is equal to the Height of the _________
