Triangles.

This morning in Room 8 for maths we investigated angles of triangles. Firstly I drew a equilateral triangle on a piece of paper.  Second I cut out the triangle I drew. Then I cut of the sides of the triangle which also known as the angles trying to make each angle the same size. I then put the angle in a pattern so that each of the angles are on the straight line with no gapes. This exercise helped me understand that a triangle is exactly 180 degrees because they make a straight line. We tried the same experiment again but instead of using the same triangle we then used a Isosceles triangle. The resulted was the same The angles were 180 degrees.
