Use the tools available to construct a perpendicular bisector of segment PQ.

Use straightedge and compass moves to construct an equilateral triangle of any size.

Here is a line [i]l[/i] with a point labeled C. Use straightedge and compass tools to try to construct a line perpendicular to [i]l[/i] that goes through C.

Use compass and straightedge tools to try to create a ray that divides angle ABC into 2 congruent angles.

Here is a line [i]l[/i] with a point labeled G. Use straightedge and compass tools to try to construct a line perpendicular to [i]l[/i] that goes through G.

Here is a line m and a point G not on the line. Use straightedge and compass moves to construct a line parallel to line m that goes through point G.

Use straightedge and compass tools to construct a square with segment GH as one of the sides.
