Part A is a rational number, so adding another rational number (1/3) gives a rational result.
Part B is 2/3, so adding 1/3 gives a sum of 1, which is still a rational number.
Part C is 2*pi, which is irrational, and adding 1/3 gives a sum of 2*pi + 1/3, which still cannot be simplified into a rational expression.
Part D is an irrational number, and 1/3 - sqrt(17) also cannot be simplified into a rational number, so this is irrational.
Therefore the correct answers to this are C & D.

Explanation:
The base can be any side.
The height is measured perpendicular to the base and is the distance to the opposite parallel side. Usually, the height is given from only one side, so that side is the base.
Sometimes, dimensions are given so that you must calculate a base or height.
