Here is a line [i]l [/i]with a point labeled [i]C[/i] :[br][br]Use straightedge and compass tools to construct a line perpendicular to [i]l[/i] that goes through [i]C[/i] .[br]
[list=1][*]Estimate the location of a point [i]D[/i] so that angle [i]DBC[/i] is approximately congruent to angle [i]CBD[/i] .[/*][*]Use compass and straightedge tools to create a ray that divides angle into 2 congruent angles. [/*][/list]
How close is the ray to going through your point [i]D[/i] ?
