This morning in Maths we investigated the angles of triangles.
1) Firstly I drew an equilateral triangle.
2) I tore off each point of the triangle leaving three equal parts.
3) I connected them like puzzle pieces and that formed a line.
4) This time we drew and cut a isosceles triangle.
5) Tearing off the angles again, I repeated the process and found that they too formed a line.
6) 180 degree is also known as a straight line.
The angles of a triangle add up to 180 degrees.
