lower quartile
A quartile deviation from some specified value, is the value or values such that a quarter of the observed values fall between these values and the specified value. Usually, but not always, the specified value is the median - the value such that have the observed values are below (and above) it. In that case, one quartile values will have a quarter of the values below it and the other will have a quarter of the values above it. The quartile deviations will be the differences between median and the two quartiles just calculated.
Yes. The prefix "quart" is derived from the word for 4, so quartile always means splitting the data into 4 sections, ie. 25%, 50%, 75%, 100%.
Not not always since an obtuse angle is always greater than 90 degrees and an acute angle is always less than 90 degrees.
This depends on what unit you are using to measure in. However, area will always be measure in (unit)^2.

Because the IQR excludes values which are lower than the lower quartile as well as the values in the upper quartile.
A percentile is always between 0% and 100%, never negative.

angle with the greatest measure
For which measure of central tendency will the sum of the deviations always be zero?
no
A measure that is always 250.
It is always better to measure by WEIGHT when baking.
shortest side
Yes.
