The relationship in this table is either
1- linear
2- exponential
because the average rate of change over each interval is
-constant
-decreases by a constant factor
-increases my a constant factor

All per-unit concepts rely on ratios, meaning, to provide a type of measurement

In the figure below, segment ac is congruent to segment ab: triangle abc with a segment joining vertex a to point d on side bc. side ab is congruent to side ac which statement is used to prove that angle abd is congruent to angle acd? segment ad bisects angle cab. triangle acd is similar to triangle abd. segment ad is congruent to segment ac. angle cab is congruent to angle cba.
