Drawing a straight line
Use the Line tool to draw straight lines at any angle. You can also draw exact horizontal, vertical, or 45-degree lines.
1.On the Formatting toolbar, click the Change Draw Tool button , then select Line.
The mouse pointer turns into a crosshair.
2.Position the crosshair where you want the line to begin, drag to where you want the line to end, then release the mouse button.
As you draw, you can adjust the angle of the line.
3.To turn the Line tool off, click the Draw button on the Formatting toolbar.
Tip: To draw a horizontal, vertical or 45-degree line, hold down the Shift key, then drag the line. As you drag, the line snaps to a 45-degree angle or a vertical or horizontal position. When finished drawing, release the mouse button first, then release the Shift key.
