## How to work with Angles: Part 2

Parallel lines and angles are everywhere. We write the number 11 with two parallel lines. But did you know these facts about the number 11?

• A total solar eclipse was observed throughout Europe on 11 August 1999 at 11:11 am.
• The number 11 is extremely popular in Canada. The maple leaf on their national flag has eleven points. In addition, many Canadian banknotes have clocks on them.  On the bank note, the time displayed on the clock  is 11 o’clock to signify the armistice. Even their one-dollar coin, also known as the Loonie, is an eleven sided polygon!
• Mariana Trench, located in the Pacific Ocean is the deepest known point on Earth. The depth is 11 km!
• 11 is the most Oscar awards won by a single film. Three films achieved this accolade, Ben Hur, Titanic and The Lord of the Rings: The Return of the King
