| Question | Answer |
| Interior angle+exterior angle= | 180 |
| sum of interior angles= | 180(n-2) |
| sum of exterior angles= | 360 |
| Interior angles in a regular polygon= | 180(n-2) -------------------- n |
| how to get the number of sides form one exterior angle= | 360 ------------ e |
| How to get the number of sides using interior angles= | e.g: i=150 e=180-150=30 n=360 divided by 30=12 sides |
| interior angle of a pentagon | 108 |
| exterior angle of a pentagon | 72 |

| How do you increase an amount | start with a given amount (100%) and you increase it by x%, then you will end up with 100+x% of the original amount. |
| How do you decrease an amount | start with a given amount (100%) and you decrease it by x%, then you will end up with 100-x% of the original amount. |
