Scott needs to fill a 3-gallon pitcher with water, but it won't fit under the faucet. he fills a 1-quart container with water from the faucet and then pours the water into the pitcher. how many times will he need to fill the 1-quart container to fill the pitcher?
how would you solve this?

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.
