Challenge 12 - Rotating triangle

[litdev]

Create a triangle shape in the center of a GraphicsWindow and rotate it left and right with arrow keys.

This is trickier than you may think NOT using an extension and will need some experimentation to work out the rules for it.

When you get this you could extend to using the line shape to make clock hands.

LitDev,

Is this what you want for this?

Hello. 

Maybe LitDev meant to create a triangle and rotate it around the center of the graphics window? 

If you just create a triangle in the center of the window and rotate it, then it's too simple.

AB,

I thought he meant to rotate the triangle around the triangle's own center. We'll see.

WHTurner,

Good program. I didn't think about showing that way!

Yes, an interesting program. 

It would be cool to be able to go back to the start screen to choose another option to watch.

Yes, that all it is - about understanding where the center of rotaion comes from for triangles and lines - the idea came from this question:

Yes this is the idea, but I was suggesting using the Shapes.Rotate command which would need more investigation into what how the rotation with triangles and lines is achieved.

Here is my effort where I try to explain how the rotation for these shapes work, DLMQ566.000

This is interesting. 

I have never faced such a task before.
