180 is a number that has several different meanings and uses. Here are a few:
1. 180 degrees is a half-turn in geometry. It means that a figure has been rotated halfway around a point, so that it is facing the opposite direction.
2. In darts, a score of 180 is the highest possible score with three darts. It is achieved by hitting three triple 20s.
3. 180 is the number of degrees in a straight line, or a line segment that forms a straight angle.
4. In Fahrenheit, 180 degrees is the temperature at which water boils.
5. In the Bible, the number 180 is associated with repentance and forgiveness. Psalm 90:10 says, "The days of our years are threescore years and ten; and if by reason of strength they be fourscore years, yet is their strength labour and sorrow; for it is soon cut off, and we fly away." This verse suggests that a person who lives to be 70 or 80 years old has the opportunity to repent and seek forgiveness for their sins.
6. 180 is also a slang term that means to make a complete turnaround or change in direction. For example, if someone says they did a 180 on a decision, they mean that they changed their mind completely and went in the opposite direction.
