Fun Balloon Day #1 This 'lab' counts as Quiz 5.
Instructions:
Take a balloon and blow it up
inside a Lenart Sphere, so everyone's balloon is about the same size.
Use a Sharpie or suitable
pen/marker to construct the triangle as explained below using ASA. Measure
the remaining angle(s) and
list them in the table below. Estimate
the area of your triangle using A~bh/2
as in plane geometry. Calculate the other quantities listed in the
table. When you're done with your
triangle, put your answers on the markerboard.
Copy the answers off the markerboard from your classmates. Use
inches for all lengths.
