Electronic spreadsheet

Today I constructed a pie chart and a bar graph using Google spreadsheet. Firstly I entered my data in the first two columns. I then selected this information and the graph.

Triangles

This morning in maths we investigated the angles of triangles. First I drew an Equal Lateral triangle. I then cut out the triangle and tore off the three corners and placed it together on a straight line. I repeated the method on a isosceles triangle. I learned that the three corners add up to 180 degrees.
