## 5.5 Examples

It takes some time and practice to feel fully at ease with the different snapping modes, especially angular snapping. Here are some examples showing what can be done with angular snapping.

#### Example 1:

We are given segments s1, s2, and e, and we want to add the dashed vertical extensions through p and q.

#### Example 2:

We are given the polygon C, and we want to draw the bracket b, indicating its vertical extension.

#### Example 3:

We want to draw the following "skyline". The only problem is to get q horizontally aligned with p.

#### Example 4:

We want to draw a line through p, tangent to C in q.

#### Example 5:

We want to draw the following "windmill". The angle of the sector and between sectors should be 30 degrees.

#### Example 6:

We want to draw a c-oriented polygon, where the angles between successive segments are multiples of 30 degrees. The automatic angular snapping mode makes this pretty easy, but there is a little catch: How do we place the ultimate vertex such that it is at the same time properly aligned to the penultimate and to the very first vertex?
