Play around with the triangles for a minute.
You can change the dimensions of the triangle by dragging the white dots on each of the angles.
You can see what happens when you put all the angles next to each other by clicking on 'slide me' and sliding it!

When you change one of the angles by dragging it, what happens to the other 2 angles?

Click on slide me so the angles move next to each other. What do you notice about what they look like when they're next to each other?

Change the triangle by dragging the white dots on the angles around. Then click on 'slide me' again to move the angles next to each other. What do you notice now?
