carlos's car has a device on it that measures how long it takes to come to a complete stop from whatever speed he was driving. the table below shows data from the device

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.

they disappear if your absent from to long. i found out that the hard way.
