5 tips for working with angles and translating them

Tips for working with corners

1. π ≈ 3.14159 - remember!

180° = π rad. This means: 1° ≈ 0.01745 rad, 1 rad ≈ 57.296°. For a quick estimate: 60° ≈ 1 rad.

2. Programming mistake #1

The functions sin(), cos(), tan() in most languages accept radians, not degrees. Always convert!

3. Arc minutes and seconds

1° = 60 arc minutes (') = 3600 arc seconds (''). Coordinate 55°45'30'' = 55.7583°.

4. Degrees for navigation

In a compass, 0° = north, 90° = east, 180° = south, 270° = west. Full rotation = 360°.

5. Angular values in CSS

In CSS: `transform: rotate(45deg)` = `rotate(0.7854rad)` = `rotate(0.125turn)`.
