Joining two lines

To be as precise as you desire, you need to first draw the vertical line. Open the properties for that line and find the y coordinate along with the height. Add the height to the y coordinate. This gives you the x coordinate position for your horizontal line (draw a line anywhere and move it to the x coordinate).To be as precise as you desire, you need to first draw the vertical line.
