2. Perform the following operation: 4(Construct) – 6:Parallel.

•This will draw a parallel to the selected line segment that passes through the selected point.

Note

You can perform a parallel construct operation while any of the following combination objects is selected.

•A single line segment and a single point, a single line and a single point, a single ray and a single point, a single vector and a single point

•One side of a polygon and a single point

uTo construct a tangent

1. Draw a circle.

2. Perform the following operation: 4(Construct) – 7:Tangent.

• This will cause the message “Select Curve” to appear.

3. Move the pointer close to the location on the circle where you want to construct the tangent.

• Move the pointer towards the circle until marks appear on it.

4. Press w.

•This will draw a line that is tangent to the circle at the location you selected with the pointer.

Note

You can perform the tangent construct operation while a circle or arc is selected.
