Using Ruler and Triangle (Set-Square)

Two cute little animations I just made: Using Ruler and Drafting Triangle (Language Note: US=Triangle, UK=Set Square)

Did I get them right?

I like it. I especially like that you're using MathsIsFun merchandise.


Why did the vector cross the road?
It wanted to be normal.

yikes You managed to decipher the text? Correct! I drafted both the Ruler and Triangle/Square. I even took the trouble to mark them in inches and cm.

The protractor got jealous!

Re: Using Ruler and Triangle (Set-Square)

Very nice. I made up a puzzle from it, too. Try to fit the protractor into the orange shape, so that it doesn't touch the orange lines at all. It's quite easy, but still, I made it up and I am proud of this achievement.

LOL!  ... maybe I should create a line of "fit the protratactor into the polygon" puzzles!

Re: Using Ruler and Triangle (Set-Square)

Rod, you are getting very good at this, I love it all!
Is it possible that you can make a thing that lets you move the protractor and the pencil around?


School is practice for the future. Practice makes perfect. But - nobody's perfect, so why practice?

Re: Using Ruler and Triangle (Set-Square)

Thanks, Rora.

You mean like place a ruler, drag the pencil and a straigh line gets draw, then place protractor and use pencil to place a dot at a certain angle?
