We are asked the following:
[tex]JK\perp TV[/tex]
"JK" and "TV" are lines where "J", "K" are points in the line JK and "T", "V" are points in the line TV. The symbol:
[tex]\perp[/tex]
Mean that the lines are perpendicular. Therefore, we need to construct lines JK and TV that are perpendicular to each other:
And thus we get the required lines.
