... 3. Use a third sheet of paper for this next item. Draw a bold pencil line and label it l , then mark a point P not on this line. Fold a strong crease into the paper to construct the perpendicular line to l that passes through P. Using your protractor as accurately as you can, what is the exact measu ...

... 1. lots of patty paper (notice that they are semi-translusent and have straight edges), and 2. a pencil. Notice that you can record distances by making marks on the paper and you can even compare two distances in this way. However, you are not to use rulers to measure distances nor protractors to me ...

Lab 3
... So far, we know that in hyperbolic geometries, triangles' angles add up to less than 180 degrees, and in elliptic geometries, triangles' angles add up to more than 180 degrees. In both cases, the difference between that sum and 180 degrees gives the area of the triangle, up to a constant. For the fo ...

Toilet paper orientation
Toilet paper when used with a toilet roll holder with a horizontal axle parallel to the floor and also parallel to the wall has two possible orientations: the toilet paper may hang over (in front of) or under (behind) the roll; if perpendicular to the wall, the two orientations are right-left or near-away. The choice is largely a matter of personal preference, dictated by habit. In surveys of US consumers and of bath and kitchen specialists, 60–70 percent of respondents prefer over.While many people consider this topic unimportant, some hold strong opinions on the matter. Advice columnist Ann Landers said that the subject was the most responded to (15,000 letters in 1986) and controversial issue in her column's history. Defenders of either position cite advantages ranging from aesthetics, hospitality, and cleanliness to paper conservation, the ease of detaching individual squares, and compatibility with a recreational vehicle or a cat. Some writers have proposed connections to age, sex, or political philosophy, and survey evidence has shown a correlation with socioeconomic status. A generic answer is that it should hang the way the person doing the roll changing prefers.Solutions range from compromise, to using separate dispensers or separate bathrooms entirely, or simply ignoring the issue altogether. One man advocates a plan under which his country will standardize on a single forced orientation, and at least one inventor hopes to popularize a new kind of toilet roll holder which swivels from one orientation to the other.
