Just for fun, try this applet while you wait for class-- is it easier to estimate a right angle when the sides are SHORT or when the sides are LONG? Try again-- is the same one closer?

## Move the blue point until the angle is as close as possible to a right angle.

We will begin on the printed notes today.

For each problem, write a conjecture based on the sequence. Then find the next item in the sequence.

#4. 4, 2, 1, 1/2, ...

2.1 #21 Percent humidity: 100%, 93%, 86%, …
