A compass and straight edge are used to create a polygon but do not limit the number of sides of the polygon created. You have to decide that separately, then use the compass and straight edge to make what you decide on.
With a straight edge and a pencil is the easiest way
An isosceles triangle has 3 sides and 2 of its sides are of equal length which can be constructed by using a straight edge and a compass.
being an archetect requires a compass, straight edge and many other tools
A ruler has markings, a straight edge does not. In "straight edge and compass" constructions, you are not allowed to mark the straight edge. Things that are impossible using only a straight edge and compass are possible if markings are allowed (for example, it's possible to trisect an angle using a marked straight edge).
False

that it could be drawn using just a compass and straight edge

A drawing created using a compass and straight edge is called a construction.See http://en.wikipedia.org/wiki/Compass_and_straightedge_constructions
A geometrical construction can be made with with a straight edge and a compass.
3 or more sides
yes it can, in fact a polygon can have any amount of sides.. just some don't have names. a polygon is a polygon as long as the lines close at an edge, its a polygon.
By bisecting a 15 degree angle with a straight edge and a compass.
False
A compass and straight edge.
