First use the parallel line tool to create line [i]a[/i] such that [i]a||f. [/i]Then create line [i]b[/i] such that [i]b||a. [/i]

How are [i]b [/i]and [i]f[/i] related?

Now use the perpendicular line tool to create line [i]a[/i] such that [i]a[/i]⏊[i]f. [/i]Then create line [i]b[/i] such that [i]b[/i]⏊[i]a. [/i]

How are [i]b [/i]and [i]f[/i] related?

Use the tools to create [i]f || a, a || b, b || c, c [/i]⏊ [i]d, d || e, e [/i]⏊ g, g || z[i].[/i]

How are [i]f [/i]and [i]z[/i] related?
