Where is the centre of enlargement.

What does centre of enlargement mean?

Where the two lines met on the grid.

What happens to the angle sizes in the corner of the shape when you enlarge it?

Translation

Translations are when you have a shape and you have the vector which looks like this.   The top number tells you that you have to move 3 to the right and the bottom number tells you that you move 2 up. I now this because if the top number is positive it moves right and if it is negative it goes left. And the bottom number if it is positive it goes up and negative goes down like this.

My answer is 45 for this question.

Monday: "Two Tens For a Five."

Bud Abbott and Lou Costello's first

scene in the movie 'One Night in the

Tropics' is a classic. 

Abbott cons Costello by simply asking

for change. "Have you got 2 tens for a

five?" he asks. As Lou realised he has

been duped, Bud snaps back: "OK, here's

your five, give me back my 2 tens!" The

skit carries on and Lou loses money! 

"Two Tens for a Five" is a classic vaudeville

routine made famous by Bud Abbott and Lou

Costello and has been repeated many times

over the years.

Here is the script!

Abbott: Have you got two tens for a five?

Costello: Just so happen to have it.

Lou gives Bud ten dollars and Bud gives Lou five dollars. Costello: Just a minute, just one minute! Abbott: Something wrong? Costello: Fifteen dollars just went south! Abbott: What do you mean? Costello: You gave me a lot of your fast talk, you said 'do you have two tens for a five' and I gave you two tens for a five. Abbott: Just a minute, are you accusing me of cheating? Costello: No, but you got two tens for a five. Abbott: Alright here's your five now gimme back my two tens. Costello: Okay, that's better. Bud gives Lou five dollars and Lou gives Bud ten dollars. After a slight pause Lou realises he has been conned again. Costello: What are you doing? Abbott: What’s wrong now?

Costello: Look Abbott, here's two tens gimme a five!

Abbott: Certainly.

Lou gives Bud ten dollars and Bud gives Lou five dollars.

Costello: HA HA HA HAAA! 

You did it to me... 

You did it to me again.

Abbott: Oh come on.

The 300 Dollar Question. 

How much did Lou lose ?
