Start by assembling a checklist of techniques for constructing segments whose length is some multiple of . For example, can you construct one with length (where is a whole number)? What about ? ... or ? What about for other values of ? (Think of a right-angled triangle in which two sides are known multiples of . What will be the length of the hypotenuse?)
