- Firstly I drew an equilateral triangle
- I cut out the triangle
- I cut all the corners off
- Then put each of the cut corners into a straight line
- After I drew a second triangle which was a isosceles triangle
- I cut out the isosceles triangle
- Then cut off the corners
- I put the cut-off corners into a straight line
I learned that 3 angles of a triangle equals up to 180 degrees.
